I'm studying for a huge exam and I have been trying to do these kinds of problems all day. I just have not been able to figure it out until just now! Thank you so much!!
It says "simplifying", not solving. So the answer is 6(sqrt)2, not 8.loadsofnumbers. If you solve for his answer then you get the same as if you solved for the original question.
I'm brushing up on my math skills for the GRE and this really helped, especially since I haven't done this since the beginning of high school. Thank you for posting this!
Finaly shit I just wanted to know how to do this again. The other guys suck, one guy took a whole page to square 3. I don't want that I just want this.
omg omg omg!!! my teacher tried explaning this shit to me but shes atotall bitch and i made no sence but u my friend my sence!!!! thank you thank you!!!
omg! thank you so much. i learned how to square root in 7th grade, but later on i kind forgot it. i spent so long trying to remember how my teacher did it (it was like this. the easy way!). i just kept finding stuff about using boxes and adding decimals....... I was about to go crazy! but this was so easy.
90 is 3*30, 30 is 3*10 and 10 is 5*2.. Therefore 90 is 3*3*5*2. Cause of the two 3s, the squareroot of 90 is 3*(squareroot of 5)*(squareroot of 2) [if we'd not split up 10 into 5*2, we'd get your teachers result 3*(squareroot of 10)]. Your "result" can be represented by 3*5*(squareroot of 2). Now it isn't hard to see, that yours (3*5*(squareroot of 2)) do NOT equals the real result 3*(SQUAREROOT of 5)*(squareroot of 2).
Hopefully I could help and apologize my orthographic and grammatic mistakes.
Thanks a ton. I got like 50 of these problems for homeworkk and was freaking out until I saw this. Can you do one with fractions and square roots being multiplied by others for future reference?
THANK YOU! I went through pages and pages of notes and still didn't understand, I wish I would have found this sooner! Just in time for finals too. Thank you so much! =)
THANK U!!!! I wish our teachers would teach us those techniques! I AM 25 YEARS OLD AND I JUST NOW UNDERSTOOD HOW TO DO THAT (finally!) and I am not a dummy, I have a 3.55 GPA in grad school, but math has never been my friend
no kiddo. I didn't drop out. I just have never been good at math. however, I came to the USA from anotehr country, I learned the language and I went to grad school here and belive it or not i graduated. Wish you luck! May be you will be a famous economist one day. BTW before you judge people - THINK! Teachers in my country do not use such methods as in this video.
i tried this with the number 1500 so i went 1500 > 5 * 300 > 5*60 >5*12>6*2>3*2 however i didn't find any "buddies" yet i know the answer is 10 square rooted to the 15...ugh exam in 7 hours...fuck...
You totally saved me. My teacher couldn't even get me to understand, and you taught me in a lesson on YouTube in 60 seconds lol. My teacher must be so proud of herself :p
89 is the 24th prime number, you'd have to do it the long way to arrive at 9.433981132056603811320660377622640716984... - Since it's irrational, you can simplify it with 283/30.

can somebody reply to my dilemma?
i tried simplying the square root of 90 and i got 15 times the square root of 2 not 3 times the square root of 10 as my teacher pointed out
i thought, using the factor tree, both methods would work but turns out they aren't equal
do perfect squares have to come first outside of radicands?
redninjastarx 1 year ago
90 is 3*30, 30 is 3*10 and 10 is 5*2.. Therefore 90 is 3*3*5*2. Cause of the two 3s, the squareroot of 90 is 3*(squareroot of 5)*(squareroot of 2) [if we'd not split up 10 into 5*2, we'd get your teachers result 3*(squareroot of 10)]. Your "result" can be represented by 3*5*(squareroot of 2). Now it isn't hard to see, that yours (3*5*(squareroot of 2)) do NOT equals the real result 3*(SQUAREROOT of 5)*(squareroot of 2).
Hopefully I could help and apologize my orthographic and grammatic mistakes.

nothing is impossible
this is the answer
all = 782
782 is 1 times 782 ...
...and 1 can be written as 1 to the power 2.
So, the 1 can just be pulled outside of the radical sign, as a 1 ,
and the other factor, the 782 , just stays inside of the radical sign.
√782 Or, = 1√728
