Question

Which of these expressions is equivalent to log(12/5)?
A. log (12) + log (5)
B. log (12) - log (5)
C. log (12) • log (5)
D. 12• log (5)

Answer 1

Answer:

B.

Step-by-step explanation:

The log of a quotient is the difference of the logs.

log (a/b) = log a - log b

log (12/5) = log (12) - log (5)

Answer: B.

Answer 2

Answer:

B) $log(\frac{12}{5})=log(12)-log(5)$

Step-by-step explanation:

Recall that $log(\frac{a}{b})=log(a)-log(b)$, therefore, $log(\frac{12}{5})=log(12)-log(5)$, making B the correct answer
