-
A.
(frac{23}{5}) -
B.
-(frac{23}{5}) -
C.
-(frac{1}{8}) -
D.
(frac{21}{7})
Correct Answer: Option C
Explanation
(frac{27^frac{1}{3} – 8^frac{2}{3}}{16^frac{2}{4} times 2})
(frac{27^frac{1}{3} – 8^frac{2}{3}}{16^frac{2}{4} times 2}) = (frac{3sqrt{27} – 3sqrt{8}^2}{sqrt{16} times 2})
(frac{3 – 4}{4 times 2})
= (frac{-1}{8})
