Question 828274: Please help.
I feel this should extremely easy, but I'm struggling. Please help.
Write the expression as the logarithm of a single number or expression with a coefficient of 1. Assume all variables represent positive numbers.

log 5 + log 10 - log 2
thanks
Answer by Edwin McCravy(20060) (Show Source): You can put this solution on YOUR website!

log(5) + log(10) - log(2) 

On the first two terms, use this rule:

Taking a log out of the addition of logs changes the
addition to multiplication:

log(5�10) - log(2)

log(50) - log(2)

On those two terms, use this rule:

Taking a log out of the subtraction of logs changes the
subtraction to division:

log

log(25)
