Question

what is 4=16^x / 4^x ?????????

Answer 1

\[4 = \frac{ 16^x }{ 4^x }\]

It looks like we can simplify the right side pretty nicely. Any ideas?

Answer 2

\(\bf 4 = \cfrac{16^x}{4^x} \implies 4\times 4^x = 16^x\\
4^{x+1} = 16^x\)

Answer 3

from there try to use the log cancellation rule of => \(\bf\huge log_aa^x = x\)

Answer 4

confused still @vramirez83 ?

Answer 5

I think this problem is made easier by noticing that 16^x / 4^x = 4^x

So, we have 4^x = 4

instead of taking a log here, what number (x), gives us 4 when we take 4 to the x power?

Answer 6

no i got it thank you (:
