Write the answer "1" for any base raised to the zero power. For instance, 3^0 = 1.
Write the answer "1" for a base within parentheses that has a zero exponent. For example, (5)^0=1.
Write the answer "1" for a base with a zero exponent that is located within a fraction. Then simplify the fraction if possible. For instance, 1/5^0 = 1/1, which is "1" when you simplify the fraction. Another example would be 2^0/6 = 1/6. This fraction is already in its simplest form.
Replace a base raised to the zero power within an addition, subtraction, division or multiplication problem as "1" and continue the operations of the problem. For instance:
4^0 + 9 = 1 + 9 = 10
7^0 - 1 = 1 - 1 = 0
20^0 / 2 = 1 / 2 = 0.5
540^0 x 40 = 1 x 40 = 40
