F. Generalization . In general, we have this rule:

1. Any number, excluding zero, with an exponent of zero is equal to one. In symbols, x0 = 1, where x≠0

2. x-n = 1/xn and xn = 1/xn, where x≠0 and n is a counting number.

As a rule, to write equivalent exponential expression of a radical expression, write the radicand as the base of the exponential expression. The reciprocal of the index becomes the exponent.

G. Application Ask the students to do Try It 3
