Radical Expressions

Helping with Simplifying,Adding, Subtracting, and Multiplying

Simplify <p>-9√15+10√15</p> <p><strong>√15</strong></p> <p>Since radicals have the same index and the same radicand, they are like radicals, so we can add them together.</p>
<p><strong>Multiply</strong></p> <p>³√16 x ³√4</p> <p>According to the rule:<sup> 3</sup>√16×<sup>3</sup>√4=<sup>3</sup>√16×4=<sup>3</sup>√64 =<sup> 3</sup>√4<sup>3</sup> = <span style="color: #888888;"><strong><span style="color: #000000;">4</span></strong></span
