I assume you don't want a calculator answer, where you simply plug it into you're calculator and get the answer (in which case, it would be 1.54919333848....etc) however, the best solution would be radical(12)/radical(5) first, convert 2.4 into a fraction. this will make it 24/10. then find the square roots of both the numerator and the denominator. radical(24)/radical(10) this can be simplified into radical(12)radical(2)/radical(5)radical(2) the radical(2)'s cancel out, and we're left with radical(12)/radical(5).
6/7
No. The two closest squares are 49 and 36. The square root of 49 being 7 and the square root of 36 being 6. you can conclude that the square root of 42 isn't a perfect square, but it's square root is between 7 and 6.

Lots of them. 6² = 36 and 7² = 49, so any number between 36 and 49 will have a square root between 6 and 7. So 37, for example, has a square root of approx 6.32 and 48 has square root of approx 6.93
