\left(\frac{\sqrt{2}}{\left(\sqrt{2}\right)^{2}}+1\right)^{2}
Rationalize the denominator of \frac{1}{\sqrt{2}} by multiplying numerator and denominator by \sqrt{2}.
\left(\frac{\sqrt{2}}{2}+1\right)^{2}
The square of \sqrt{2} is 2.
\left(\frac{\sqrt{2}}{2}+\frac{2}{2}\right)^{2}
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{2}{2}.
\left(\frac{\sqrt{2}+2}{2}\right)^{2}
Since \frac{\sqrt{2}}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.
\frac{\left(\sqrt{2}+2\right)^{2}}{2^{2}}
To raise \frac{\sqrt{2}+2}{2} to a power, raise both numerator and denominator to the power and then divide.
\frac{\left(\sqrt{2}\right)^{2}+4\sqrt{2}+4}{2^{2}}
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(\sqrt{2}+2\right)^{2}.
\frac{2+4\sqrt{2}+4}{2^{2}}
The square of \sqrt{2} is 2.
