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
