Rationalize the denominator: 2%2F%28sqrt%282%29-1%29
a) 2%2F%28sqrt%282%29%2B1%29
b) sqrt%282%29-1
c) 2sqrt%282%29%2B1
d) sqrt%282%29%2B1
e) none of these
2%28sqrt%282%29%2B1%29%2F%28%28sqrt%282%29-1%29%28sqrt%282%29%2B1%29%29
%282sqrt%282%29%2B2%29%2F%28sqrt%284%29%2Bsqrt%282%29-sqrt%282%29-1%29
%282sqrt%282%29%2B2%29%2F%282-1%29
%282sqrt%282%29%2B2%29%2F1
2sqrt%282%29%2B2
The answer is either none of these or one of these answers could be:
2%28sqrt%282%29%2B1%29 Is another look to the answer with 2 factored out.
Happy Calculating!!!
