Ineed the answer to all 3 of these questions i need this tomorrow

1) 3^3=27 and 4^2=16. Negative numbers (if in brackets) keep their minus if the exponent is an odd number, or turn into positive if their exponent is even. So, (-3)^3 would be -27 and (-4)^2 is 16. The value would be -27*16, or -432

3. This would be -4, since the number isnt in brackets. This would be the equivalent of -(2)^2.

I dont have time to answer 2 right now but I hope this helped.
