If \(P=\sqrt{\frac{rs^3}{t}}\), express r in terms of p, s and t
A
\(\frac{p^2 t}{s^3}\)
B
\(\frac{p^3 t}{s^3}\)
C
\(\frac{p^3 t}{s^2}\)
D
\(\frac{p^ t}{s^3}\)
Ask EduPadi AI for a detailed answer
Correct Option: A
\(P=\sqrt{\frac{rs^3}{t}}\=
P^2 =\frac{rs^3}{t}\\ tp^2 = rs^3\\ r = \frac{p^2 t}{s^3}\)
