q = p\(\sqrt{r}\)
q = p3r
q = pr3
q = pr\(\frac{1}{3}\)
Correct answer is D
p\(\frac{1}{3}\) = \(\frac{3\sqrt{q}}{r}\)(cross multiply)
3\(\sqrt{q}\) = r x 3\(\frac{\sqrt{q}}{r}\)(cross multiply)
3\(\sqrt{q}\) = r x 3\(\sqrt{p}\) cube root both side
q = 3\(\sqrt{r}\) x p
q = r\(\frac{1}{3}\)p = pr\(\frac{1}{3}\)
