3^-2 = 0.111111111........

3.2^-4 = 9.536743164 (-03)

Thanks in advance (I expected some more 'normal' numbers to be the answers as we are not meant to use calculators on this bit!)

3^(-2) = 1 / 3^2 = 1/9 = .11111.... correct

3.2^(-4) = 1 / (3.2^4) = .00953674... = 3.53674 e-3
you're correct, and I don't know how to easily figure that out without a calculator

Your Answers ARE CORRECT

3^(-2)=1/[3^(+2)]=(1/3)(1/3)=1/9

Divide 9 into1.0000000000000000000000000 will keep repeating 1's

3.2^(-4)=1/(3.2^4)=1/[(3.2)(3.2)(3.2)(…

do long multiplication get 104.8576

1/104.8576
