Section 7.1: Radical Expressions and Rational Exponents

Example 9. Simplify each radical expression after ﬁrst re-writing the expression in exponential form. List

each simpliﬁcation in radical form.

(a)

(b)

(d)

A general approach to simplifying expressions with radicals and/or rational exponents:

Answers are considered fully simpliﬁed in both radical form and exponential form.

If you are given an expression in radical form, state your fully simpliﬁed answer in radical form.

You will probably use the rules of exponents in your work; make sure to convert back to radical

form in the end.

If you are given an expression in exponential form, state your fully simpliﬁed answer in

exponential form. Never leave negative exponents in your fully simpliﬁed answer.

Some problems do not ask you to fully simplify, but instead ask your to convert an expression

from one form to another. If this is the case, don’t make the problem more work than necessary!
