If \(p=\sqrt{\frac{rs^3}{t}}\), express r in terms of p, ...
If \(p=\sqrt{\frac{rs^3}{t}}\), express r in terms of p, s and t?
\(\frac{p^2 t}{s^3}\)
\(\frac{p^3 t}{s^3}\)
\(\frac{p^3 t}{s^2}\)
\(\frac{p^ t}{s^3}\)
Correct answer is A
\(p =\sqrt{\frac{rs^3}{t}}\\=
p^2 =\frac{rs^3}{t}\\
tp^2 = rs^3\\
r = \frac{p^2 t}{s^3}\)
