A) \[3.968\]
B) \[\frac{1}{3.968}\]
C) \[1.984\]
D) \[\sqrt{0.504}\]
Correct Answer: C
Solution :
\[\frac{1}{\sqrt{5}-\sqrt{3}}=\frac{1}{\sqrt{5}-\sqrt{3}}\times \frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}+\sqrt{3}}\] \[=\frac{\sqrt{5}+\sqrt{3}}{2}=\frac{3.968}{2}=1.984\]You need to login to perform this action.
