# Which expression is equivalent to log18 - log(p + 2)?

logStartFraction 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

**Solution:**

Logarithm is nothing but another way of expressing exponents and can be used to solve problems that cannot be solved using the concept of exponents only.

It is known from logarithmic property,

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

Therefore

log(18) - log(p+2) = log[18/(p + 2)]

The correct alternative is therefore log StartFraction 18 Over p + 2 EndFraction

## Which expression is equivalent to log18 - log(p + 2)?

**Summary:**

The expression equivalent to log18 - log(p + 2) is log StartFraction 18 Over p + 2 EndFraction
