2 Definition of a Natural Number Exponent If b is a real number and n is a natural number,
3 The Negative Exponent Rule If b is any real number other than 0 and n is a natural number, then
4 The Zero Exponent RuleIf b is any real number other than 0,b0 = 1.
5 The Product Rule b m · b n = b m+n When multiplying exponential expressions with the same base, add the exponents. Use this sum as the exponent of the common base.
6 The Power Rule (Powers to Powers) (bm)n = bm•nWhen an exponential expression is raised to a power, multiply the exponents. Place the product of the exponents on the base and remove the parentheses.
7 The Quotient RuleWhen dividing exponential expressions with the same nonzero base, subtract the exponent in the denominator from the exponent in the numerator. Use this difference as the exponent of the common base.
