\frac{5}{4}f=\frac{5}{\sqrt{k}-3}
The equation is in standard form.
\frac{\frac{5}{4}f}{\frac{5}{4}}=\frac{5}{\frac{5}{4}\left(\sqrt{k}-3\right)}
Divide both sides of the equation by \frac{5}{4}, which is the same as multiplying both sides by the reciprocal of the fraction.
f=\frac{5}{\frac{5}{4}\left(\sqrt{k}-3\right)}
Dividing by \frac{5}{4} undoes the multiplication by \frac{5}{4}.
f=\frac{4}{\sqrt{k}-3}
Divide \frac{5}{-3+\sqrt{k}} by \frac{5}{4} by multiplying \frac{5}{-3+\sqrt{k}} by the reciprocal of \frac{5}{4}.
