2^-3 or 2^-33

Can u show me how u did it??

Thank you very much

Answer 1

The first one is very close to the cube root of 2. There is no easy way to calculate that by hand, but of course a calculator would have no problem. In the old days you would calculate it using a table of logarithms, but I don't think anybody does that any more.

Negative powers can be converted in positive powers of the reciprocal, so 2^-3 = (1/2)^3 = 1/8

Answer 2

You should be able to put those into a calculator.
