Question

( frac{1}{sqrt{5}+sqrt{6}-sqrt{2}} times frac{(sqrt{5}+sqrt{6})+(sqrt{2})}{(sqrt{5}+sqrt{6})+(sqrt{2})} )
( (sqrt{5}+sqrt{6})+sqrt{2} )
( (sqrt{5}+sqrt{6})^{2}-(sqrt{2})^{2} )
( frac{(sqrt{5}+sqrt{6})+sqrt{2}}{5+6+2 sqrt{80}-2}=frac{(sqrt{5}+sqrt{6})+sqrt{2}}{2 sqrt{20}+9} )

# 18. Rationalise the denominator - 15+56-52
