# Is root of $$x^2$$ = $$x$$ ?

Given that:

$\large \color{blue} \sqrt{ \left( \frac{3}{2} \right)^2 } = \color{red} \frac{3}{2} \\ \large \color{blue} \sqrt{ \left( \frac{1}{2} \right)^2 } = \color{red} \frac{1}{2}$

Find the value of:

$\large \color{blue} \sqrt{ \left( - \frac{1}{2} \right)^2 } = \color{red} ?$
