Question

Which expression is equivalent to log18 – log(p + 2)?
log StartFraction p + 2 Over 18 EndFraction
log StartFraction 18 Over p + 2 EndFraction
log StartFraction 20 Over p EndFraction
log left-bracket 18 times (p + 2) right-bracket

Answer 1

Use the log quotient rule: log A − log B = log(A/B). So

log 18 − log(p + 2) = log(18/(p + 2)).

Answer: log(18/(p + 2)).
