The easiest way to do this is with a calculator. Anyway, the definitions are as follows.

x to the power 1/2 is the square root of x, x to the power 1/3 is the cubic root of x, and in general, x to the power 1/n is the nth. root of x.

If you also have a number other than one in the numerator:

For example, to calculate x to the power 3/5 you first raise x to the power 3, then take the fifth root of the result. You can also do it the other way: first calculate the fifth root, then raise to the third power. In general, to calculate x to the power m/n, you take the nth root, then raise the result to the power m.

### Log -3 equals?

There is no answer - it is an error: negative numbers do not have logarithms. The log if a number tells to what power the (positive) base must be raised to get the number. Raising any positive number to any power will never result in a negative number, so it is an error to try and take the log of a negative number.
