What is the simplified form of 3a^4b^-2c^3?
What is -a^-2 if a = -5?
D No -1/(-5)^2 = -1/25 so C
What is (-m)^-3n if m = 2 and n = -24?
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
Thank you so much! Just one quick question...is it a rule to always simplify first and then substitute, as in question 2?
That is up to you.
