Answer
12$s^{1/2}$$t^{1/3}$
Work Step by Step
You are given $\frac{12s^{\frac{5}{2}}t^{\frac{7}{3}}}{s^2t^2}$.Simplify the expression:
12$s^{5/2-2}$$t^{7/3-2}$ -since you are dividing powers with the same base, subtract the exponents-
$\frac{5}{2}$-2=$\frac{1}{2}$ and $\frac{7}{3}$-2=$\frac{1}{3}$.
The simplified expression is 12$s^{1/2}$$t^{1/3}$
