In the equation below, , , and are non-zero numbers. What is the value of in terms of and ?

$\frac{1}{m^3}-\frac{1}{k^2}=\frac{1}{p}$

$m=(\frac{p+k^2}{2})^3$

$m=\frac{p^2k^3}{p+k^2}$

$m=p^{\frac{1}{2}}-k^{\frac{1}{3}}$

$m=(\frac{p+k^2}{pk^2})^{\frac{1}{3}}$

$m=(\frac{pk^2}{p+k^2})^{\frac{1}{3}}$
