Question

Answer it quickly. I have bit dificulty in it

Answer 1

Explanation:

Firts what you need to do is to have same bases:

8^n = 16^4

(2^3)^n = (2^4)^4

2^3n = 2^16

And now when your bases are equal then your exponents must be equal too so:

3n = 16

n=16/3

Answer 2

Use logarithms.
Log base 8 of 16^4 equals n
n=log(16^4)/log(8)
