The expression ( 4 \sqrt{5} ) is already in its simplest form. The coefficient 4 cannot be simplified further with the square root of 5, as 5 is not a perfect square. Therefore, ( 4 \sqrt{5} ) remains as it is.
They are +/- 4*sqrt(5).

It is simplified as 4 times the square root of 3. Hope this helps! dancinggirl25
As a simplified surd, it is 5*sqrt(15)
15 square root sign 5
9 times the square root of 5
√25 + √75 = 5 + √(25*3) = 5 + √25√3 = 5 + 5√3.
