How do you evaluate g(x)=log_ax for x=a^2?

g(x)=2

Explanation:

Inputting a^2 for x, we get

g(x)=log_a(a^2)

At this point, the key realization here is that we can leverage the logarithm property

log_a(a)=1

log_a and a cancel each other out, so we essentially have

g(x)=cancel(log_a)(cancela^2)

=>g(x)=2

Hope this helps!
