Question

rationalise the denominator 2underoot3 -underoot5/2underoot 2 +3 underoot 3

Answer 1

just change the sign and multiply and divide by same term.

Answer 2

$\frac{2 \sqrt{3} - \sqrt{5} }{2 \sqrt{2} + 3 \sqrt{3} } \times \frac{2 \sqrt{2} - 3 \sqrt{3} } { 2 \sqrt{2} - 3 \sqrt{3} }$
$\frac{4 \sqrt{6} - 18 - 2 \sqrt{10 } + 3 \sqrt{15} }{8 - 27}$
$\frac{4 \sqrt{6} - 18 - 2 \sqrt{10 } + 3 \sqrt{15} }{ - 19}$
