A negative power means the same as 1 over the positive power.
|x-3 = 1/x3||2-3 = 1/23 = 1/8|
If the power is 1, this is the same as the number without a power.
|x1 = x||21 = 2||2-1 = 1/21 = 1/2|
If the power is 0, the term has the value 1.
|x0 = 1||20 = 1||googolplex0 = 1|
A power written as a unit fraction means the root of the term.
A non-unit fraction means take the power of the numerator and the root of the denominator; order is not important.
x1/2 = √x
y-1/2 = 1/√y
81/3 = 3√8 = 2
x5/2 = √(x5)=(√x)5
