It really helps to add parentheses to clarify what is being "square rooted".
PROBLEM 1:
√(9/25)
= √9 / √25
= 3/5
PROBLEM 2:
Did you mean the following?
√(27 - 2) / 3
= √25 / 3
= 5/3

If you mean sqrt(9/25) = sqrt(3^2/5^2)
= sqrt( (3/5)^2)
= 3/5.
if you mean sqrt(27 - 2/3)
= sqrt( (81 - 2)/3)
= sqrt( 79/3). done.
