Remove parentheses.
\[usem\imath d-po\imath ntmethod=\]
Add \(po\imath ntmethod\) to both sides.
\[usem\imath d=po\imath ntmethod\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[usem\imath d=p{o}^{2}\imath n{t}^{2}mehd\]
Regroup terms.
\[usem\imath d=e\imath p{o}^{2}n{t}^{2}mhd\]
Cancel \(e\) on both sides.
\[usm\imath d=\imath p{o}^{2}n{t}^{2}mhd\]
Cancel \(m\) on both sides.
\[us\imath d=\imath p{o}^{2}n{t}^{2}hd\]
Cancel \(\imath \) on both sides.
\[usd=p{o}^{2}n{t}^{2}hd\]
Cancel \(d\) on both sides.
\[us=p{o}^{2}n{t}^{2}h\]
Divide both sides by \(s\).
\[u=\frac{p{o}^{2}n{t}^{2}h}{s}\]
u=(p*o^2*n*t^2*h)/s
