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.
Guidelines and rules to using when performing mathematical operations with exponents.
