Question

I can't remember how to do this, can someone help me to find an equivalent expression (4^2)^5

A.) 4^7
B.)4^10
C.)16^7
D.)16^10

Answer 1

B.)4^10 is correct Bro:)
If you will calculate it on calculator, you will know your answer by yourself.
E.g:- 4^2=16, therefore 16^5=1048576
Hence 4^10=1048576
that means we multiplied powers:)

Answer 2

4^10

4 ^2(5) = 2x 5 = 10

if4^2 + 4^5 then it will 4^2+5 = 4^7

but here in this question comes 4^10
