Of the following, which is greatest?
A) (1/5) ^ -2
B) (1/3) ^ -2
C) 3^-2
D) 5^-2
E) 2^3
A is the right answer. I thought so too but wasn't exactly sure on the rules. Would you change A to 5^2? If so, what are the exact rules for this one. I know that 3^-2 is (1/3)^2.... would you flip A using the same rule?
