Simplify: (32)4 (3 • 3) (3 • 3) (3 • 3) (3 • 3) = 38 To simplify a number with an exponent that is being raised to another exponent, multiply the two exponents. Raising a Power to a Power: (am)n = amn
Simplify: (y2)5 (y2) (y2) (y2) (y2) (y2) = y2•5 = y10 To simplify a number with an exponent that is being raised to another exponent, multiply the two exponents. (am)n = amn
