sqrt%282%29%2Fsqrt%287%29
Multiply both the numerator and the denominator by sqrt%287%29
%28sqrt%282%29%2Asqrt%287%29%29%2F%28sqrt%287%29%2Asqrt%287%29%29
The denominator multiplies out to become 7 and the numerator becomes sqrt%2814%29
So the answer is sqrt%2814%29%2F7
The reason for simplifying the original problem, is that convention says to never leave a
radical in the denominator. Get rid of it by multiplying it by itself.
Hope this helps you.
