In this lesson, we will learn five exponential rules and how to apply 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.
