Here are a few more worked problems. Study them to acquaint yourself with the use of different operations you can perform with exponents.
This problem combines a cube root with the multiplicative inverse of a value:
In this instance, the negative exponent (–1/3) calls for the multiplicative inverse of the cube root of 8. Having expressed the problem in this form, you can then extract the root and arrive at 1/2.
This problem involves working with both a negative exponent and the need to simplify an expression that involves a root and a power:
With this problem, you begin by dealing with the negative exponent. You change ...
