Question

$$\left. \begin{array} { l } { \sqrt { h ^ { 2 } } = \sqrt { 144 } } \\ { h = } \end{array} \right.$$

Answer

h=0

Solution


Simplify  \(\sqrt{{h}^{2}}\)  to  \(h\).
\[h=\sqrt{144}h\]
Since \(12\times 12=144\), the square root of \(144\) is \(12\).
\[h=12h\]
Subtract \(h\) from both sides.
\[0=12h-h\]
Simplify  \(12h-h\)  to  \(11h\).
\[0=11h\]
Divide both sides by \(11\).
\[0=h\]
Switch sides.
\[h=0\]
