Simplify the surd 3√ 20 +√ 45 ​
melisa1 [442]

Answer:

9\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify the radicals

\sqrt{20}

= \sqrt{4(5)}

= \sqrt{4} × \sqrt{5}

= 2\sqrt{5}

\sqrt{45}

= \sqrt{9(5)}

= \sqrt{9} × \sqrt{5}

= 3\sqrt{5}

Then

3\sqrt{20} + \sqrt{45}

= 3(2\sqrt{5} ) + 3\sqrt{5}

= 6\sqrt{5} + 3\sqrt{5}

= 9\sqrt{5}
