Given: x = </p><p>\frac{\sqrt{3}}{2}

To find: </p><p>\frac{1+x}{1+\sqrt{1+x}}+\frac{1-x}{1-\sqrt{1-x}}

\frac{1+x}{1+\sqrt{1+x}}+\frac{1-x}{1-\sqrt{1-x}}

Put Value of x in fiven expresion we get,

\frac{1+\frac{\sqrt{3}}{2}}{1+\sqrt{1+\frac{\sqrt{3}}{2}}}+\frac{1-\frac{\sqrt{3}}{2}}{1-\sqrt{1-\frac{\sqrt{3}}{2}}}

\frac{\frac{2+\sqrt{3}}{2}}{1+\sqrt{\frac{2+\sqrt{3}}{2}}}+\frac{\frac{2-\sqrt{3}}{2}}{1-\sqrt{\frac{2-\sqrt{3}}{2}}}

\frac{\frac{2+\sqrt{3}}{2}}{1+\sqrt{\frac{4+2\sqrt{3}}{4}}}+\frac{\frac{2-\sqrt{3}}{2}}{1-\sqrt{\frac{4-2\sqrt{3}}{4}}}

\frac{\frac{2+\sqrt{3}}{2}}{\frac{2+\sqrt{4+2\sqrt{3}}}{2}}+\frac{\frac{2-\sqrt{3}}{2}}{\frac{2-\sqrt{4-2\sqrt{3}}}{2}}

\frac{2+\sqrt{3}}{2+\sqrt{4+2\sqrt{3}}}+\frac{2-\sqrt{3}}{2-\sqrt{4-2\sqrt{3}}}

\frac{(2+\sqrt{3})(2-\sqrt{4-2\sqrt{3}})+(2-\sqrt{3})(2+\sqrt{4+2\sqrt{3}})}{(2+\sqrt{4+2\sqrt{3}})(2-\sqrt{4-2\sqrt{3}})}

\frac{4-\sqrt{12-6\sqrt{3}}+2\sqrt{3}2\sqrt{4-2\sqrt{3}}+42\sqrt{3}-\sqrt{12+6\sqrt{3}}+2\sqrt{4+6\sqrt{3}}}{4+2\sqrt{4+2\sqrt{3}}-2\sqrt{4-2\sqrt{3}}-\sqrt{16-12}}

\frac{8-\sqrt{12-6\sqrt{3}}-\sqrt{12+6\sqrt{3}}+2\sqrt{4+2\sqrt{3}}-2\sqrt{4-2\sqrt{3}}}{2+2\sqrt{4+2\sqrt{3}}-2\sqrt{4-2\sqrt{3}}}

\frac{8-(3-3)-(3+\sqrt{3})+2(1+\sqrt{3})-2(1-\sqrt{3})}{2+2(1+\sqrt{3})-2(1-\sqrt{3})}

\frac{8-6+\sqrt{3}-\sqrt{3}+2-2+2\sqrt{3}+2\sqrt{3}}{2+2+2\sqrt{3}-2+2\sqrt{3}}

\frac{2+2\sqrt{3}+2\sqrt{3}}{2+2\sqrt{3}+2\sqrt{3}}

⇒  1
