A) 8.661
B) 4.331
C) 1.7321
D) \[-1.732\]
Correct Answer: C
Solution :
Expression \[=\sqrt{192}-\frac{1}{2}\sqrt{48}-\sqrt{75}\] \[=\sqrt{64\times 3}-\frac{1}{2}\sqrt{64\times 3}-\sqrt{25\times 3}\] \[=8\sqrt{3}-\frac{1}{2}\times 4\sqrt{3}-5\sqrt{3}\] \[=8\sqrt{3}-2\sqrt{3}-5\sqrt{3}=\sqrt{3=}1.7321\]You need to login to perform this action.
