Question 149709
Multiply top and bottom by {{{3*sqrt(2) - 2*sqrt(3)}}}
{{{((3*sqrt(2) - 2*sqrt(3)) / (3*sqrt(2) + 2*sqrt(3))) * ((3*sqrt(2) - 2*sqrt(3)) / (3*sqrt(2) - 2*sqrt(3)))}}}
{{{(3*sqrt(2) - 2*sqrt(3))^2 / (18 - 12)}}}
{{{(18 - 12*sqrt(6) + 12) / 6}}}
{{{(30 - 12*sqrt(6)) / 6}}}
{{{5 - 2*sqrt(6)}}} answer
