How to solve this question 4^n = 64

=64

Step-by-step explanation:

we know that

4×4×4=64

and we can write it as

=64

comparing it with

=64

=

according to  exponent rule when basis are equal the powers should be equal  as well

=

in this case basis are equal i.e 4

so powers should also be equal

and hence we get

n=3

hence answer is

=64

a. is correct
