Question

If $\sqrt{3}=1.7$ then $\sqrt{147}+2\sqrt{27}$ is $32.3$

• A. True
• B. False

Answer 1

The correct option is A

True

Given: $\sqrt{3}=1.7$

$\sqrt{147}+2\sqrt{27}$ = $\sqrt{3\times 49}+2\sqrt{3\times 9}$

= $(\sqrt{3}\times \sqrt{49})+(2\sqrt{3}\times 2\sqrt{9})$

=$(1.7\times 7)+\left[\right(2\times 1.7)\times (2\times 3\left)\right]$

= $11.9+20.4$

= $32.3$
