Question 80
$$\frac{2}{\sqrt{10 + 2\sqrt{21}}} - \frac{1}{\sqrt{12 + 2\sqrt{35}}} - \frac{1}{\sqrt{8 + 2\sqrt{15}}} =$$
Solution
given that
= $$\frac{2}{\sqrt{10 + 2\sqrt{21}}} - \frac{1}{\sqrt{12 + 2\sqrt{35}}} - \frac{1}{\sqrt{8 + 2\sqrt{15}}} $$
we know that $$\sqrt{21}$$ = 4.58 , $$\sqrt{35}$$ = 5.91 , $$\sqrt{15}$$ = 3.87
put the value in the equation we get
= $$\frac{2}{\sqrt{19}} - \frac{1}{\sqrt{19}} - \frac{1}{\sqrt{19}} $$
