To solve the equation ( \log(x) - \log(2) = 1 ), you can use the properties of logarithms. Start by combining the logarithms using the quotient rule:

[ \log(x) - \log(2) = \log\left(\frac{x}{2}\right) ]

Now, rewrite the equation with the combined logarithm:

[ \log\left(\frac{x}{2}\right) = 1 ]

To eliminate the logarithm, exponentiate both sides of the equation with base 10:

[ 10^{\log\left(\frac{x}{2}\right)} = 10^1 ]

[ \frac{x}{2} = 10 ]

Now, solve for ( x ):

[ x = 2 \cdot 10 ]

[ x = 20 ]

So, the solution to the equation ( \log(x) - \log(2) = 1 ) is ( x = 20 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
