In this lesson, we will learn five rules of exponent and how to use them.

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
