Evaluating exponents with negative numbers?
These questions just popped up on my homework and I'm pretty confused at to how to solve them.
(-3) to the power of -3.
and
2(-2/5) to the power of -2.
It'd be really helpful if you tell me how you got to the answers as well since there are more like them.
Also please don't include symbols like ^ because I'm learning this whole thing in french and for some reason those kind of symbols haven't shown up/haven't been taught.
Thanks!

(-3) to the power of -3, to get rid of the negative in the exponent use the reciprocal
(-1/3) to the power of 3
(-1/27)
2(-2/5) to the power of -2, same thing here
2(-5/2) to the power of 2
2(25/4)
25/2
