Answer : 1
Step-by-step explanation:
To evaluate your expression, I just need to use three simple points about logarithms, namely:
log(1)=0
log(a/b)=log(a)−log(b)
logn(n)=1
Using point 2 to rewrite your expression, we have:
[log(1)−log(2)]+[log(2)−log(3)]+...+[log(8)−log(9)]+[log(9)−log(10)]
=log(1)−log(10)
Using point 2 to rewrite your expression, we have:
[log(1)−log(2)]+[log(2)−log(3)]+...+[log(8)−log(9)]+[log(9)−log(10)]
=log(1)−log(10)
Using point 2, this simplifies to: −log(10)
The actual answer depends on what base logarithm you are using. I will assume that you are using common logs (aka decimal logs or base-10 logs), in which case, from point 3, the expression reduces to −1
