Answer:
m = 15
Step-by-step explanation:
to solve this question we have it to be
4^m÷4^5 = 4^3
from the question , we are going to cross multiply
we have,
4^5 × 4^ 3 = 1 × 4 ^m( since the right hand side has the same base(4) we can pick one )
4^ 5 ×3 = 4^m
multiply through by 1/4
1/4 × 4^ 5×3 = 1/4 × 4^m
5×3 = m
15 = m
therefore the value of m = 15
