A) 2
B) -1
C) -3
D) 4
Correct Answer: D
Solution :
(d): \[\frac{\sqrt{5}-\sqrt{3}}{\sqrt{5}+\sqrt{3}}\times \frac{\sqrt{5}-\sqrt{3}}{\sqrt{5}-\sqrt{3}}=\frac{{{\left( \sqrt{5}-\sqrt{3} \right)}^{2}}}{2}\] \[=\frac{8-2\sqrt{15}}{2}=4-\sqrt{25}\therefore a=4,b=-1\]You need to login to perform this action.
