Question

Which expression is equivalent to the given expression. pls help :)

Answer 1

B

Explanation:

`(a^(m))/(a^(n))=a^(m-n)\\\\\\(a^(m))^(n) =a^(mn)`

`((4m^(2)n)^(2))/(2m^(5)n)=(4^(2)(m^(2))^(2)n^(2))/(2m^(5)n)\\\\\\=(16m^(4)n^(2))/(2m^(5)n)\\\\\\=(8m^(4)n^(2))/(2m^(5)n)\\\\\\=8m^((4-5))n^((2-1))\\\\\\=8m^(-1)n`
