at the beggining of the video i was really confused at the end i knew more about exponential functions thanks sal :)

I was getting really annoyed that you kept repeating "1/4 multiplied by 1/4..." Then I realized what you did there lol. Thanks for getting me to the correlation stage of learning.

They never get to zero... Do you have to naturally kill the last one?

I Kind of understood, but I just started and I really didn’t know were to start but this was able to help me get an idea I guess.

But if its 1/3 ^-3 why isnt that the same as 1/3•1/3. Bevpcause cant you write a negative number as the fraction. I'm confused how your getting 3^3 out of it instead.

[xoom]

what the heck at 2:34 he wrote 3^3=81, it's actually 27!

[deanhoenselaar]

its going to be a very stupid question here but why is y never a negative number ? is it only because the base is positive i expected the -x to have negative answer? X.X sorry trying to get this ?

I would like to know what software do you use to write in this video?

Anyone watching this in 2024, just me okay …..

I bet if someone were to examine my brain, they'd find some physical deformity that causes me to be retarded in this kind of math :(.  :'(

Can the base ever be negative. If not, why.

how did 1/3^-3 is equal to 81?
my brain n calcu saying it’s 27, ,

because, 1/3^-4 is equal to 81, ,

isn’t right? please enlighten meT^T
