Leave in radical form means don't simplify the sqrt (radical) to exact value.
Example, exact value of (sqrt(2))= 1.4142
All your answers are correct.
Always simplify radicals, ie,(like you did), but wasn't sure,
(sqrt(52)) = 2(sqrt(13)) don't leave as
(sqrt(52))
(sqrt(20) = 2(sqrt(5)) don't leave as
(sqrt(20)
