Question

Solve: $\left(16\sqrt{2}\right)\times \left(14\sqrt{2}\right)$

• A. $224$
• B. $224\sqrt{2}$
• C. $448$
• D. $448\sqrt{2}$

Answer 1

Answer: (C)

$448$

We have $16\sqrt{2}\times 14\sqrt{2}$, this can also be written as

$=16\times 14\times \sqrt{2}\times \sqrt{2}=224\times 2$ $(\because \sqrt{2}\times \sqrt{2}=2)$

$=448$
