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)
