Simplified Radicals A radical is simplified if it does not have any perfect squares as a factor in the radical. Perfect Squares 12 = 1 62 = 36 112 = 121 162 = 256 22 = 4 72 = 49 122 = 144 172 = 289 32 = 9 82 = 64 132 = 169 182 = 324 42 = 16 92 = 81 142 = 196 192 = 361
Radical Expressions with Different Indices. To apply the product or quotient rule for radicals, the indices of the radicals involved must be the same. If the indices are different, then first rewrite the radicals in exponential form and then apply the rules for exponents. Example 14: Multiply: 2 ⋅ 2 3.
with the radical sign. Study Tip In Example 1b, although 34 = 81 and (− 3)4 = 81, √4 — 81 = 3 because the radical symbol indicates the positive root. Rational Exponents Words The nth root of a positive number a can be written as a power with base a and an exponent of 1/n. Numbers √ 4 — 81 = 811/4 Algebra √n —a = a1/n
A better way to approach this is to use exponents. Exponential notation is an easier way to write a number as a product of many factors. Base Exponent. The exponent tells us how many times the base is used as a factor. For example, to write 2 as a factor one million times, the base is 2, and the exponent is 1,000,000.
Solving Radical Equations To solve a radical equation, follow these steps: Step 1 Isolate the radical on one side of the equation, if necessary. Step 2 Raise each side of the equation to the same exponent to eliminate the radical and obtain a linear, quadratic, or other polynomial equation.
