Rules of Exponents Review: Exponents represent repeated multiplication.

Exponents to the Zero power What happens when you raise a number to the zero power? (b 0 )

Exponent to the Zero Power

We see that any base raised to the zero power equals 1. What happens when you raise an exponent to a negative exponent? b -a

Negative Exponents 3 4 = 81 3 3 =27 3 2 =9 3 1 =3 3 0 =1 3 -1 = ?

Negative Exponent (2 3 )(2 -3 )

Negative Exponent
