Which choices are equivalent to the expression below? check all that applies please

andre [41]

Choices A, C and F work. This is because when in radical form, you may dive or subtract as long as you keep the sign. The square root of 9 is 3 and the square root of 4 is 2. When you solve it, the answer is 6. Hope this helped!
