Answer 1

Answer:

Step-by-step explanation:

$\frac{1}{2+\sqrt{22}+\sqrt{26}}\\\\=(\frac{1}{\sqrt{2}})(\frac{1}{\sqrt{2} + \sqrt{11}+\sqrt{13}})\\\\=\frac{1}{\sqrt{2}}(\frac{1}{\sqrt{2} + \sqrt{11}+\sqrt{13}})(\frac{\sqrt{2} + \sqrt{11}-\sqrt{13}}{\sqrt{2} + \sqrt{11}-\sqrt{13}})\\\\=\frac{\sqrt{2} + \sqrt{11}-\sqrt{13}}{(\sqrt{2})(2\sqrt{22})}\\\\=\frac{\sqrt{2} + \sqrt{11}-\sqrt{13}}{\sqrt{2}(2)(\sqrt{2})(\sqrt{11})}\\\\=\frac{\sqrt{2} + \sqrt{11}-\sqrt{13}}{4\sqrt{11}}\\\\On \;\;Comparison\\\\a=11\\\\b=2$
