Option 1: 250
Option 2: 252
Option 3: 253

Question : The value of $\frac{1}{\sqrt{17+12 \sqrt{2}}}$ is closest to _____.
Option 1: 1.4
Option 2: 1.2
Option 3: 0.14
Option 4: 0.17
Correct Answer: 0.17
Solution : Given expression, $\frac{1}{\sqrt{17+12 \sqrt{2}}}$ $=\frac{1}{\sqrt{{3^2}+(2\sqrt2)^2+2\times3\times2\sqrt2}}$ $=\frac{1}{\sqrt{(3+2\sqrt2)^2}}$ $=\frac{1}{3+2\sqrt2}$ $=\frac{1}{3+2\sqrt2}\times\frac{3-2\sqrt2}{3-2\sqrt2}$ $=\frac{3-2\sqrt2}{3^2-(2\sqrt2)^2}$ [As $a^2-b^2=(a-b)(a+b)$] $=\frac{3-2\sqrt2}{9-8}$ $=3-2\sqrt2$ $=3-2\times1.414$ = 3 – 2.828 = 0.172 Hence, the correct answer is 0.17.
