The square root of 48 in radical form is 4√3.
√3
3 square root 10
root 57 in radical form is √57 since 57 = 3 x 19 and there are no square factors.
So I assume you mean the square root and square root of 27=square root of (9x3)=3(square root (3))
5 times the square root of 3
It is 3 times the square root of 17
Square root of 324 is 18 or 3 times the square root of 2
3√10
5√3
7√3
The rules for "standard radical form" are that (a) there should be no perfect square within the radical sign; for example, square root of 12 is equal to square root of 4 x square root of 3 = 2 x square root of 3, and should be written as the latter; and (b) there should be no radical sign in the denominator. For example, if you have 1 / square root of 2, you multiply top and bottom by the square root of 2, to get a square root in the numerator, but none in the denominator.
