This self-worksheet allows students to strengthen their skills at using multiplication to simplify radical expressions.All radical expressions in this maze are numerical radical expressions. The radicand in the denominator determines the factors that you need to use to rationalize it. When the denominator (divisor) of a radical expression contains a radical, it is a common practice to find an equivalent expression where the denominator is a rational number. Now you can apply the multiplication property of square roots and multiply the radicands together. Step One: Simplify the Square Roots (if possible) In this example, radical 3 and radical 15 can not be simplified, so we can leave them as they are for now. \\ & = \frac { \sqrt { 10 x } } { 5 x } \end{aligned}\). Simplifying Radical Worksheets 23. The key to learning how to multiply radicals is understanding the multiplication property of square roots. % Rationalize the denominator: \(\frac { \sqrt { x } - \sqrt { y } } { \sqrt { x } + \sqrt { y } }\). That is, numbers outside the radical multiply together, and numbers inside the radical multiply together.
