Question

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

Answer 1

Answer:

$C. =log\frac{1}{5}$

Step-by-step explanation:

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

consider a and b two real numbers

where a > 0 and b > 0.

$log\frac{a}{b} =loga-logb$

……………………………………………………………

log 3 − log 15

$=log\frac{3}{15}$

$=log\frac{3}{3\times 5}$

$=log\frac{1}{5}$

Answer 2

Answer:

C log(1/5)

Step-by-step 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)
