The value of m is 8.
<h3>What is Exponents and powers?</h3>
The amount of times a number has been multiplied by itself is shown by its exponent. The result of multiplying 8 by itself n times is represented as follows:
8 x 8 x 8 x 8 x …..n times = 
Given:

Now, solving for m
= 16
= 
Taking the quad root we have
m -4 = 4
m = 4+ 4
m = 8
Hence, the value of m is 8.
