Answer:


15√(x)

Explanation:


√((25*9)x)

Start by "taking out" the perfect squares. 25 and 9 are perfect squares (and pretty common ones).

The square root of 25 is 5 and the square root of 9 is 3. Therefore you can take out a 5 and 3 from the radical. Multiply the numbers you take out together.

5 * 3 = 15

The number outside of the radical sign will be a 15, and x is left over inside the radical. The final answer is
15√(x).
