Mercury · Answer

old question but - 
for square roots, if the number under the radical (√) is a perfect square, then the whole expression is rational
otherwise it's irrational

recall that perfect squares are squares of integers (so 1^1 = 2, 2^2 = 4, etc.)

if all else fails, plug the answer choices into a calculator and see which one gives you a non-integer
