#### Answer

C does not equal to 25n

#### Work Step by Step

We can find the answer through process of elimination A= $(5n^{\frac{1}{2}})^{2}$ =$(5)^{2}(n^{\frac{1}{2}})^2$ =25n ; it equals 25n to it is not the correct answer B= $(5n^{\frac{1}{2}})(5n^{\frac{1}{2}})$ =25n ; it equals 25n to it is not the correct answer D=$5^{2}(n^{\frac{2}{3}})^{\frac{3}{2}}$ =25n ; it equals 25n to it is not the correct answer Therefore, we must conclude that C is the correct answer
