Question Number 59763 by ANTARES VY last updated on 14/May/19
((2+(√3))/( (√2)+(√(2+(√3)))))+((2+(√3))/( (√2)−(√(2−(√3)))))  simplify.
$$\frac{\mathrm{2}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}+\sqrt{\mathrm{2}+\sqrt{\mathrm{3}}}}+\frac{\mathrm{2}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}−\sqrt{\mathrm{2}−\sqrt{\mathrm{3}}}} \\ $$$$\boldsymbol{\mathrm{simplify}}. \\ $$

(√(2+(√3)))=(√((4+2(√3))/2))  (√(2+(√3)))=((1+(√3))/( (√2)))  (√(2−(√3)))=(((√3)−1)/( (√2)))  ((2+(√3))/( (√2)+(√(2+(√3)))))+((2+(√3))/( (√2)−(√(2−(√3)))))  =(2+(√3))((1/( (√2)+((1+(√3))/( (√2)))))+(1/( (√2)−(((√3)−1)/( (√2))))))  =(2+(√3))(((√2)/(3+(√3)))+((√2)/(3−(√3))))  =(√2)(2+(√3))(((3−(√3)+3+(√3))/6))  =(√2)(2+(√3))
$$\sqrt{\mathrm{2}+\sqrt{\mathrm{3}}}=\sqrt{\frac{\mathrm{4}+\mathrm{2}\sqrt{\mathrm{3}}}{\mathrm{2}}} \\ $$$$\sqrt{\mathrm{2}+\sqrt{\mathrm{3}}}=\frac{\mathrm{1}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}} \\ $$$$\sqrt{\mathrm{2}−\sqrt{\mathrm{3}}}=\frac{\sqrt{\mathrm{3}}−\mathrm{1}}{\:\sqrt{\mathrm{2}}} \\ $$$$\frac{\mathrm{2}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}+\sqrt{\mathrm{2}+\sqrt{\mathrm{3}}}}+\frac{\mathrm{2}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}−\sqrt{\mathrm{2}−\sqrt{\mathrm{3}}}} \\ $$$$=\left(\mathrm{2}+\sqrt{\mathrm{3}}\right)\left(\frac{\mathrm{1}}{\:\sqrt{\mathrm{2}}+\frac{\mathrm{1}+\sqrt{\mathrm{3}}}{\:\sqrt{\mathrm{2}}}}+\frac{\mathrm{1}}{\:\sqrt{\mathrm{2}}−\frac{\sqrt{\mathrm{3}}−\mathrm{1}}{\:\sqrt{\mathrm{2}}}}\right) \\ $$$$=\left(\mathrm{2}+\sqrt{\mathrm{3}}\right)\left(\frac{\sqrt{\mathrm{2}}}{\mathrm{3}+\sqrt{\mathrm{3}}}+\frac{\sqrt{\mathrm{2}}}{\mathrm{3}−\sqrt{\mathrm{3}}}\right) \\ $$$$=\sqrt{\mathrm{2}}\left(\mathrm{2}+\sqrt{\mathrm{3}}\right)\left(\frac{\mathrm{3}−\sqrt{\mathrm{3}}+\mathrm{3}+\sqrt{\mathrm{3}}}{\mathrm{6}}\right) \\ $$$$=\sqrt{\mathrm{2}}\left(\mathrm{2}+\sqrt{\mathrm{3}}\right) \\ $$
