Answer:

Step-by-step explanation:

[tex]\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}\\\\[/tex]

                          [tex]= (2 + 3 + 4) \sqrt{2}\\\\= 9\sqrt{2}[/tex]
