Step-by-step explanation:
One of the logarithm rules states the following:
![log{a} - log{b} = log{\frac{a}{b}}](https://tex.z-dn.net/?f=log%7Ba%7D%20-%20log%7Bb%7D%20%3D%20log%7B%5Cfrac%7Ba%7D%7Bb%7D%7D)
For this problem, that means the following:
![log{2x + 3} - log{x - 1} = log{\frac{2x + 3}{x - 1}}](https://tex.z-dn.net/?f=log%7B2x%20%2B%203%7D%20-%20log%7Bx%20-%201%7D%20%3D%20log%7B%5Cfrac%7B2x%20%2B%203%7D%7Bx%20-%201%7D%7D)
So now we have the following:
![log{\frac{2x + 3}{x - 1}} = 3](https://tex.z-dn.net/?f=log%7B%5Cfrac%7B2x%20%2B%203%7D%7Bx%20-%201%7D%7D%20%3D%203)
Rolling the log, we get the following:
![10^{3} = \frac{2x + 3}{x - 1}](https://tex.z-dn.net/?f=10%5E%7B3%7D%20%3D%20%5Cfrac%7B2x%20%2B%203%7D%7Bx%20-%201%7D)

Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
