for some reason, mathematiciansdo not like square roots on a denominator. Why? God knows.

Anyway, we therefore need to "rationalise the denominator". We do this, in this sort of simple case, by multiplying by 1 (but written as a fraction)...as:

sqrt%281%2F2%29
sqrt%281%29%2Fsqrt%282%29
1%2Fsqrt%282%29 --> now multiply by "1"
%281%2Fsqrt%282%29%29%2A1 --> but written as the second fraction
%281%2Fsqrt%282%29%29%2A%28sqrt%282%29%2Fsqrt%282%29%29
sqrt%282%29%2F%28sqrt%282%29%2Asqrt%282%29%29
sqrt%282%29%2F2

done.
