Question 64101
Rationalize the denominator: {{{2/(sqrt(2)-1)}}}

a) {{{2/(sqrt(2)+1)}}}
b) {{{sqrt(2)-1}}}
c) {{{2sqrt(2)+1}}}
d) {{{sqrt(2)+1}}}
e) none of these

{{{2(sqrt(2)+1)/((sqrt(2)-1)(sqrt(2)+1))}}}
{{{(2sqrt(2)+2)/(sqrt(4)+sqrt(2)-sqrt(2)-1)}}}
{{{(2sqrt(2)+2)/(2-1)}}}
{{{(2sqrt(2)+2)/1}}}
{{{2sqrt(2)+2}}}
The answer is either none of these or one of these answers could be:
{{{2(sqrt(2)+1)}}} Is another look to the answer with 2 factored out.
Happy Calculating!!!
