Answer
$\frac{x}{25}$
Work Step by Step
You have ($\frac{3x^1{^/}{^2}}{15}$$)^{2}$. Simplify the expression:
($\frac{x^1{^/}{^2}}{5}$$)^{2}$ -simplify the coefficients-
$\frac{(x^1{^/}{^2})^2}{5^2}$ -apply exponent rule ($\frac{a}{b}$$)^{c}$=$\frac{a^c}{b^c}$-
($x^{1/2}$$)^{2}$=x and $5^{2}$=25
=$\frac{x}{25}$
