Evaluate – \(16\sqrt {\frac34} – 9\sqrt \frac 34 \: \: \: \text {If } \: \sqrt {12} = 3.46\)
Evaluate /मूल्यांकन करें:
\(16\sqrt {\frac{3}{4}} – 9\sqrt{\frac {4}{3}} \: \text {If } \: \sqrt {12} = 3.46\)
Detailed Solution & Logic
Correct Answer:
3.46
Solution:
$16\sqrt{\frac{3}{4}}-9\sqrt{\frac{4}{3}}$
$=16\times\frac{\sqrt{12}}{4}-9\times\frac{\sqrt{12}}{3}$
$=4\sqrt{12}-3\sqrt{12}$
$=\sqrt{12}$
Given $\sqrt{12}=3.46$
Therefore,
Answer = 3.46
