Question 185441: Assume that x is a positive number use the logarithm properties to present the expression log (x+10)-log x as the logarithm of a single quanity.
a) log x/x+10
b) log x+10/x
c) none of these
d) log 10 Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! "log rules" say:
log a - log b = log a/b
.
Therefore,
log (x+10)-log x
= log ((x+10)/x)
.
It looks like of the choice given
b) log x+10/x
is the closest
However, because of the the "order of precedence" it does NOT equal:
log ((x+10)/x)
.
I would say your answer is:
c) none of these
