Question

Which of the following is equivalent to the expression below?
log 3-log 15

Answer 1

C log(1/5)

Explanation:

log 3-log 15 = -log _10^(5)

log 5 = log _10^(5)

log (-12) = log _10^(-12)

log (1/5) = -log _10^(5)

log 12 = log _10^(12)

Answer 2

`C. =log(1)/(5)`

Explanation:

Formula =======================

consider a and b two real numbers

where a > 0 and b > 0.

`log(a)/(b) =loga-logb`

……………………………………………………………

log 3 − log 15

`=log(3)/(15)`

`=log(3)/(3* 5)`

`=log(1)/(5)`
