Question: Solve the resulting problems if the given changes are made in the indicated examples of this section. In Example 4(b), change the exponent to 3/2.

Solve the resulting problems if the given changes are made in the indicated examples of this section.

In Example 4(b), change the exponent to −3/2.


Data from Example 4(b)

4-1/2 1 41/2 || (C) 93/2 = (91/2)3 = 33 27


We note in (b) that Eq. (11.6) must also hold for negative rational exponents. In writing 4−1/2 as 1/41/2, the sign of the exponent is changed.

4-1/2 1 41/2 || (C) 93/2 = (91/2)3 = 33 27
