| \[\frac{\sqrt{(180)}\times \sqrt{(18)}\times \sqrt{(5)}\times \sqrt{(3)}}{\sqrt{(96)}\times 5}=?\] |
A) \[5\frac{1}{2}\]
B) \[2\frac{3}{4}\]
C) \[1\frac{1}{2}\]
D) \[4\frac{1}{2}\]
E) \[5\frac{2}{3}\]
Correct Answer: D
Solution :
| \[\frac{\sqrt{180}\times \sqrt{18}\times \sqrt{5}\times \sqrt{13}}{\sqrt{96}\times 5}=\sqrt{\frac{180\times 18\times 5\times 3}{96\times 25}}\] |
| \[=\sqrt{20.25}=4.5=4\frac{1}{2}\] |
