Hello! This is an easy problem but I am having difficulty finding the right answer. What I am doing is simplifying square root of 0.25r^6 to 0.25^4 but then non of the answer choices make sense.

- If r > 0, then square root of 0.25r^6 =

(A) 0.05r ^3

(B) 0.05r^4

(C) 0.05r^5

(D) 0.5r^2

(E) 0.5r^3
