Simplify \(Simpq\imath py\sqrt{7s}ubset\times 3\sqrt{7}\) to \(3Sie\imath mpqpyubst\sqrt{7s\times 7}\).
\[3Sie\imath mpqpyubst\sqrt{7s\times 7}+67\]
Simplify \(7s\times 7\) to \(49s\).
\[3Sie\imath mpqpyubst\sqrt{49s}+67\]
Use this rule: \(\sqrt{ab}=\sqrt{a}\sqrt{b}\).
\[3Sie\imath mpqpyubst\sqrt{49}\sqrt{s}+67\]
Since \(7\times 7=49\), the square root of \(49\) is \(7\).
\[3Sie\imath mpqpyubst\times 7\sqrt{s}+67\]
Take out the constants.
\[(3\times 7)mppqyubs\sqrt{s}tSie\imath +67\]
Simplify \(3\times 7\) to \(21\).
\[21mppqyubs\sqrt{s}tSie\imath +67\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[21m{p}^{1+1}qyub{s}^{1+\frac{1}{2}}tSie\imath +67\]
Simplify \(1+1\) to \(2\).
\[21m{p}^{2}qyub{s}^{1+\frac{1}{2}}tSie\imath +67\]
Simplify \(1+\frac{1}{2}\) to \(\frac{3}{2}\).
\[21m{p}^{2}qyub{s}^{\frac{3}{2}}tSie\imath +67\]
Regroup terms.
\[21Sie\imath m{p}^{2}qyub{s}^{\frac{3}{2}}t+67\]
Regroup terms.
\[67+21Sie\imath m{p}^{2}qyub{s}^{\frac{3}{2}}t\]
