A) 1.00
B) 1.25
C) 1.50
D) 2.25
Correct Answer: A
Solution :
(a): Rationalizing each term, \[\frac{\sqrt{6.25}-\sqrt{5.25}}{1}+\frac{\sqrt{4.25}-\sqrt{3.25}}{1}+\frac{\sqrt{5.25-\sqrt{4.25}}}{1}+\frac{\sqrt{3.25}-\sqrt{2.25}}{1}\]\[=\sqrt{6.25}-\sqrt{2.25}=2.5-1.5=1\]You need to login to perform this action.
