Which of the following is equivalent to the log of 1 ninth over k ?
Answer
A
log times 1 ninth divided by log k
B
log times 1 ninth times log k
C
log 1 ninth minus log k
D
log 1 ninth plus log k
Explanation
Use the quotient rule for logarithms: log(a/b) = log(a) − log(b). So log((1/9)/k) = log(1/9) − log(k), which matches choice D, “log 1 ninth minus log k.”
