D YES
What is a^2 if a = 5?
a. 25
b. 25
c. 1/25
d. 1/25
D No 1/(5)^2 = 1/25 so C
What is (m)^3n if m = 2 and n = 24?
a. 3
b. 3
c. 4
d. 4
A NONE OF THESE. 2^72 is huge. You have a TYPO

It is not 3n. It is (m)^3 n. So it would be .125* 24, which is how I did it.

[(m)^3 ] n
[1/(2)^3] (24)
(1/8)(24)
3
YES A

Thank you so much! Just one quick question...is it a rule to always simplify first and then substitute, as in question 2?
