A) 0
B) -1
C) 2
D) 5
Correct Answer: A
Solution :
(a): \[2log\left( \frac{5}{8} \right)+log\left( \frac{128}{125} \right)+log\left( \frac{5}{2} \right)\] \[=log{{\left( \frac{5}{8} \right)}^{2}}+log\left( \frac{128}{125} \right)+log\left( \frac{5}{2} \right)\] \[=\log \frac{{{5}^{2}}\times 128\times 5}{{{8}^{2}}\times 125\times 2}\] \[=log\,1=0\]
