Question

Which is the following sum in simplest form sq rt 8 +3 sq rt 2+ sq rt 32

Answer 1

Answer:

Step-by-step explanation:

$\sqrt{8} = \sqrt{2*2*2}=2* \sqrt{2} = 2\sqrt{2}\\\\ \sqrt{32} = \sqrt{2* 2 * 2 * 2 * 2} = 2*2* \sqrt{2} = 4\sqrt{2}\\\\ \sqrt{8}+3 \sqrt{2} + \sqrt{32} = 2\sqrt{2} + 3\sqrt{2} + 4\sqrt{2}$

                          $= (2 + 3 + 4) \sqrt{2}\\\\= 9\sqrt{2}$
