How to Rewrite Radical and Exponential Expressions - Solving questions in a radical form can be difficult; thus, it can be easier to rewrite the equation in rational exponents. You can write an equation to exponential form by using these steps. Let us give an example where you have to solve 3 √82 . Now, by the first look, it can be difficult to solve. To convert it into exponential expressions, you can rewrite them as: 3 √82 = 82/3. Now, you can further break down the expression as follows: 82/3 = (81/3)2. Now, it’s in exponential form, which is easier to solve. The cube root of 8 is two, and by squaring it, the result becomes 4. A series of worksheets and lessons that will show you how to rewrite both radical and exponential expressions.
