Question

$${ \left( \frac{ \sqrt{ 2 } }{ { \left( \sqrt{ 3 } \right) }^{ 2 } - \frac{ 1 }{ \frac{ 1 }{ 2 } } } \right) }^{ 2 }$$

Answer

2

Solution


Remove parentheses.
\[{(\frac{\sqrt{2}}{{\sqrt{3}}^{2}-\frac{1}{\frac{1}{2}}})}^{2}\]
Use this rule: \({\sqrt{x}}^{2}=x\).
\[{(\frac{\sqrt{2}}{3-\frac{1}{\frac{1}{2}}})}^{2}\]
Invert and multiply.
\[{(\frac{\sqrt{2}}{3-2})}^{2}\]
Simplify  \(3-2\)  to  \(1\).
\[{(\frac{\sqrt{2}}{1})}^{2}\]
Simplify  \(\frac{\sqrt{2}}{1}\)  to  \(\sqrt{2}\).
\[{\sqrt{2}}^{2}\]
Use this rule: \({\sqrt{x}}^{2}=x\).
\[2\]
