Change of Base Formula for Logarithms

[maria1239876]

why is it always log base 10??

[patrickJMT]

@maria1239876 i am pretty sure i touch on this in the video: a calculator can do log base 10, so i use it.

[robinfr93]

can you help me out with this sum, its been bugging me forever now..

I tried solving it even by your method still got the wrong answer as it was not the provided answer..

Can you please help me out with it??

Sorry for typing it like this,theres some problem with youtube on typing it the right way as it gives me an error..

Oh btw your awesome man!!!

Keep up the good work..

I watched your Cancellation properties video, now, watched this video. I have never been more clearer than this. However, one thing confused me. Can "change of base formula" be replaced to cancellation "second" property from your video? If I do that, the log will be cancelled, only domain will be left.

[oakkathebest]

Ignore Ignore pls. I realized it should be done with equation. haha. 

[RespectMyHate]

Since it's in the base you want to put him in the basement, HA HA.
