That is basically a cubed root. If you know the cubes (1, 8, 27, 64, 125, ...) then you can estimate the value of n(1/3) where n = any number.

'''(one third) to the power (negative one) = three'''
Divide by 3
It is: 1,000,000 = one million
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.
One third times nine to the eighth power equals 14,348,907
