Exponent Rules Part 2

[ShineyMew7]

You are soooooo helpful! Thank you so much!

[kerolification]

like lprotonl said, how can we repay you? you should at least put an ad on this so you can make at least some money of of it.

[lollylee69]

Please HELP:Can't you on the last problem-- ((3^2)*(9^8))^-2 make it ((9)^1)*(9)^8)^-2 THEN (9^7)^-2 THEN 9^-14 Wouldn't this be the same thing?? Hope you get what I'm asking...

[bitsofplastic]

thank you!!!

[Thew26XppX]

this is so handy. help me get my SAT scores up! thank you

[vediocamera]

@Thew26XppX How can you study well for SAT and what type of questions are there on it?

[JRxxAKAxxNOZY]

i would love to go to a school with teachers like this guy T_T

[lilauz]

thanks a lot Mr. Khan!

[punkdudes2000]

my teacher gave me this problem 6x6x6x2 how do you show that in an exponent?

[metaldave08096]

6 to the third power times 2

[Realisticz16]

Thank you! When that last equation came up i paused the video and worked it out. Based on what you showed before, i used a different method and came up with the same answer. I despise math generally so that was great, normally i'd have to do it the long way.

[titinta3]

After over two decades of detesting math and having nightmares about math, I finally get it! If only i had an awesome teacher like you-back in the day! Thank you! I am currently a freelance writer, but now my appetite for math is refreshingly addictive

[lordsxman]

great video thanks for your contribution

[DaleLaV]

Very helpful and nicely explained.

[hoiszhdfoifh22]

Brilliant. I can do algebra now. And I am useless at maths. Jesus christ, man, thankyou so much for this stuff. Especially the DNA one. Helped a bunch.

[Br0nXb0y96]

please come to my school and teach

[OkayCompuuter]

I wish you were my math teacher!

[desirearmelle]

thanks .but how do you approach a problem with different bases

[iSmiffy95]

@desirearmelle Basically if your given a problem with different bases e.g: 2^3 x 5^3 there is no more you can do with it because its all in its most simplified form .

[feinart2009]

thanks dude you made me get an A- on my math test! :-)

[raykasprowicz]

Thank you! Another excellent video on exponents.

[riccovieira]

thank you soooo much man! wish more people could do videos like this!

very very good!

[missaman93]

this = very helpful all algebra students shud watch this

[vasquezg86]

I thought when you have (2 x 9)^100, you multilply 2 and 9 because they are in PARENTHESES and then solve it by it's exponent. (P.E.M.D.A.S.) So my question is why did you instead do the exponent to each one first 2^100 x 9^100 then just left like that?????

[nicholsjoshua15]

God bless you my friend, I know there is a special place in heaven for you, and people like you.

[tommygun415]

Very Informative. Listening carefully can spark sudden realizations! It's amazing. Thanks.

[perhapslovehurts]

Thanks . you really helped a lot . I appreciate it a lot (:

[nenax24x]

What if you had (-3)^7 X (-3)^3 is that equal to -3^10 or would it be a positive??

[youcandomathtoo]

@nenax24x No it wouldn't be positive, because of your original base which is negative. So yeah, the soulution would be: -3^10.

[RebornAc3]

God bless you Sal!!!!!!!!!

[aimasood]

GREAT JOB , 

[pennclick]

Really good and easy to understand!

[MarvelsofaLifetime]

Aren't in many senses, the third and fourth laws for exponents kind of the same thing. Because really, when you are prescribing the exponent to the numbers within the parentheses, you are essentially just multiplying the exponent by 1 to all the numbers within the parentheses.

[mickeymouselover1998]

these vids rlly help me a lot:D

[rancic]

Indeed this is the only way to learn anything...this is applicable...but simply remembering rules and formulas is stupid...everything else is bull....Salman...Thank you...and i can understand your satisfaction from this...beautyful :)

[rancic]

kibur jou`re stupid as fuck! So do fuck off to twilight trailers!

[kibur914]

my dad showed me this site and i dont like it but it gave me an excuse to be on youtube when i am not supposed to so tanks sal

[SaraPunkzz]

THANK YOU SO MUCH

[scraper1000]

Really helpful. But in school we are learning problems a bit more advanced like: x^-3 y^3 . 3x^0

and

m^2 n^-3 / 2nm^3

So maybe if you could make a video on those, than that would be great.

[sk8tterpriincessss]

i agree, i think that trying to prove to yourself that that is how something works is a lot better, because like you said, if you memorize them, you can forget them eventually , thank you !!

[JackMoranRain]

Are there separate videos with exercises or something? thanks

[yumihitomi]

this is very helpful!

[alstrup69]

AWESOME!! I wish I found this years ago...

THANKS FOR CREATING THESE VIDEOS!!!

[Wafflesmart]

gee, how confusing.

But still...

Thanks for all the help!

[TheTmagic]

2:00 Why isn't it equal to 32^50?

Thank you!!!!

[ecto98]

.....your kidding right, this guy is better than great, he has gotten me through 5th, 6th, working on 7th, and im sure he'll help through the rest.

[seldemitria]

hmm i guess this is ok

[lprotonl]

u took time of urs to create this beautiful lesson and the very least i can do is take a sec to say THANKS!

[qrais]

@lprotonl dont need to, google gave him 2 million dollars.

[ktrel54]

You are an absolute genius mate. I can't possibly thank you enough! You're more to the point, easier to follow AND you get through it in half the time of my teacher, who's works at one of the best schools in Australia. Thanks again.

[sirsagan]

@ktrel54 I'm just gona throw it out there that i knew you would be an aussie after i saw "mate" :P

tho i fully agree that hes a genius and helps a lot of people

[Vanderjuice]

Thanks for making all of these. I'm brushing up on my math skills, basically for the fun of it. I'm incredibly grateful for these videos; I can't imagine how grateful those are who actually require these.

[chla15]

nerds

[fangs1234]

you rock brah lets be friends

[PureInsanity00]

nice vid

[adam700r]

2 times 7 is in parentheses, it seems that the answer should have been 14 to the 3rd power if you were to solve the parentheses first and the exponents second.I may be wrong because im new to this. But if you have a explanation for my confusion it would be greatly appreciated.

[mlehbleh22]

Your right.

[diamondstinger]

No, if you look closely 2, has the exponent attached. In no way would that be 14. That's 2 multiplied by itself 7 times. = 128 Let the professor do his thing.

[adam700r]

I believe we are all wrong, (except the professor)we are suppose to distribute the exponent into each base in the parentheses, third power of 2 is 8, of 7 is 343, so simplified it would be 8 times 343 equals 2744. I think i made the mistake of not understanding the distributive property, thank you sal for the vids, you are making the world a better place.

[morrisdn]

Actually you can look at it either way. If you watch earlier in the video he multiplies out. You could have grouped them together (2x2x2x7x7x7) in this case it is more apparent that as 2^3X7^3. You could have also left them in combination ((2x7)x(2x7)x(2x7)). If you left it as such a combination it would then be 14^3. Different ways of writing the same thing thats all. Do not get confused.

[morrisdn]

Actually the exponent is attached to both the 2 and the 7 as noted by the parenthesis, so in this case it could be looked at as (14)^3. You are correct though that is the exponent was just attached to the 2

[N3SLiiiHAN]

thankkk u :D

[Fiorucci79]

Thank you so much for this lesson! It's amazing to be able to find this here. I really appreciate this video and cannot thank you enough, take care.

[jolzar14]

thank yew this helped out alot
