Question

Please brake down why !

Answer 1

Answer:

D

Step-by-step explanation:

using the rule of radicals

• $\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplifying $\sqrt{32}$

$\sqrt{32}$ = $\sqrt{16(2)}$ = $\sqrt{16}$ × $\sqrt{2}$ = 4$\sqrt{2}$

$\sqrt{32}$ + 5$\sqrt{2}$

= 4$\sqrt{2}$ + 5$\sqrt{2}$ = 9$\sqrt{2}$ → D
