The following table give the Exponent Rules. Scroll down the page for examples and solutions.
The rules of exponent are:
Product Rule:
When we multiply two powers that have the same base, add the exponents. 32 x 35 = 37
Power Rule:
When we raise a power to a power, multiply the exponents.
(32)5 = 310
Quotient Rule:
When we divide two powers with the same base, we subtract the exponents.
36 ÷ 32 = 34
Zero Rule:
Any nonzero number raised to the power of zero equals 1.
540 = 1
Negative Rule:
Any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.
2-3 = 1/23
