Evaluate: y=(1+(1)/(2))^2

Expression: $y={\left( 1+\frac{ 1 }{ 2 } \right)}^{2}$

Calculate the sum

$y={\left( \frac{ 3 }{ 2 } \right)}^{2}$

To raise a fraction to a power, raise the numerator and denominator to that power

$\begin{align*}&y=\frac{ 9 }{ 4 } \\&\begin{array} { l }\begin{array} { l }y=2 \frac{ 1 }{ 4 },& y=2.25\end{array},& y={\left( \frac{ 3 }{ 2 } \right)}^{2}\end{array}\end{align*}$
