Answer 1

Answer:

Slight correction, you are not after a solution but the value of an expression.

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, 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
