Simplify the expression below.
If the 3f isn't under the radical in the original expression, then it's C.
You just take the 4 out from under the radical. It should be +2 though.
As follows:
\(\sqrt{\frac{4e}{3f}}=\sqrt{\frac{4\times3ef}{9f^2}}=\frac{2}{3f}\sqrt{3ef}\\ \text{or just }\frac{2\sqrt{3ef}}{3f}\)
