1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) We have seen that \(\sqrt[3]{-64}=-4\). A power can be undone with a radical and a radical can be undone with a power. m a √ = b if bm = a The small letter m inside the radical is called the index. Assume the variables represent positive real numbers. E. SIMPLIFY RADICALS WITH NO PERFECT ROOT Not all radicands are perfect squares, where when we take the square root, we obtain a positive integer. Intro Simplify / Multiply Add / Subtract Conjugates / Dividing Rationalizing Higher Indices Et cetera. Now we will remove this restriction. For example, if we input √8 in a calculator, the calculator would display 2.828427124746190097603377448419… Courtesy of Harold Hiken . Intermediate Algebra Skill Simplifying Radical Expressions: Index 2 or Higher Simplify. P Worksheet by Kuta Software LLC Kuta Software - Infinite Algebra 2 Name_____ Simplifying Radicals Date_____ Period____ Simplify. 2. Step 3: Move each group of numbers or variables from inside the radical to outside the radical. This Higher Roots and Rational Exponents Worksheet is suitable for 9th Grade. Assume the variables represent positive real numbers. When we worked with square roots that had variables in the radicand, we restricted the variables to non-negative values. There should be no fractions under the radical sign. Square Roots and Other Radicals Sponsored by The Center for Teaching and Learning at UIS Page | 1 Radicals - Definition Radicals, or roots, are the opposite operation of applying exponents. 1) 75 5 3 2) 16 4 3) 36 6 4) 64 8 5) 80 4 5 6) 30 The odd root of a number can be either positive or negative. Some techniques used are: find the square root of the numerator and denominator separately, reduce the fraction and change to improper fraction. The pdf worksheets cover topics such as identifying the radicand and index in an expression, converting the radical form to exponential form and the other way around, reducing radicals to its simplest form, rationalizing the denominators, and simplifying the radical expressions.

For the second root, we needed a second copy. Geometry G Name_____ Simplifying Radicals Worksheet 1 Simplify. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. Simplifying Radicals. Simplify Radicals with variables - Cube Roots Date_____ Period____ Simplify. Exponents & Radicals Worksheets Exponents and Radicals Worksheets for Practice. Certain radicands presented here are neither perfect cubes nor perfect squares. There should be no radicals in the denominator (i.e. I can distinguish between a rational and irrational number.

It goes into a lot of detail on what radicals are, the difference between irrational and rational numbers and how to simplify radicals.
