A negative number to an even power is even.
A negative number to an odd power.
Parentheses take precedence over exponentiation
A unary - takes precedence over exponentiation, so -(-2) would first be converted to +2 prior to the exponentiation
Exponentiation takes precedence over multiplication, so
in the 3(-4)^3 problem, you do the exponentiation first, then multiply

You just need to know (if you honestly don't already!) that two negatives make a positive, a negative and a positive make a negative and anything in brackets needs to be worked out first. The rest is easy.
