( left(frac{1+sqrt{2}}{sqrt{5}+sqrt{3}}right)+left(frac{1-sqrt{2}}{sqrt{5}-sqrt{3}}right) ) ( frac{(1+sqrt{2})(sqrt{5}-sqrt{3})+(1-sqrt{2})(sqrt{5}+sqrt{3})}{(sqrt{5}+sqrt{3})(sqrt{5}-sqrt{3})} ) ( sqrt{5}-frac{sqrt{3}+sqrt{10}-sqrt{6}+sqrt{5}+sqrt{3}-sqrt{10}-sqrt{6}}{(sqrt{5})^{2}-(sqrt{3})^{2}} frac{10 sin 9}{(a+b)(a-b)=a^{2}-b^{2}} ) ( =frac{2 sqrt{5}-2 sqrt{6}}{2} ) Take 2 comnon & cancel it isth Lenominator ( sqrt{5}-sqrt{6} )
