General Solution Steps: Step 1. Isolate the Radical(s) and identify the index (n). Step 2. Raise both sides of the equation to the “nth” power. Step 3. Use algebraic techniques (i.e. factoring, combining like terms,...) to isolate the variable. Repeat Steps 1 and 2 if necessary. Step 4. Check answers.

Print this page. 6.2 FRACTIONAL EXPONENTS AND RADICAL EXPRESSIONS. A radical expression is an expression involving roots. For example, is the positive number whose square is a. Thus, since. 32 = 9, and since 252 = 625. Similarly, the cube root of a, written , is the number whose cube is a. So since. 43 = 64.
