How to Subtract Logarithms: Step-by-Step Guide

Subtracting logarithms can be straightforward once you understand the properties that govern them. In your problem, you have \\( ext{log}_7(50) - ext{log}_7(5)\\). To tackle this, we apply the logarithmic subtraction property, which states that when you subtract two logarithms with the same base, you can rewrite the expression as the logarithm of the division of the two arguments. Specifically, this means: \\( ext{log}_b(M) - ext{log}_b(N) = ext{log}_b\left(\frac{M}{N}\right)\\).

Let’s break down the steps:

1. **Identify the logs**: You have \\( ext{log}_7(50)\\) and \\( ext{log}_7(5)\\).
2. **Apply the property**: According to the logarithmic subtraction property, you rewrite it as:

\\( ext{log}_7(50) - ext{log}_7(5) = ext{log}_7\left(\frac{50}{5}\right)\\).
3. **Simplify the fraction**: Calculate \\(rac{50}{5}\\), which equals 10.
4. **Final result**: Thus, we get \\( ext{log}_7(10)\\).

Now you can see why \\( ext{log}_7(50) - ext{log}_7(5)\\) equals \\( ext{log}_7(10)\\). This property not only saves you time but also helps simplify complex logarithmic expressions.

### Real-World Applications of Logarithms
Logarithms are widely used in various fields, including science, engineering, and finance. Understanding logarithmic properties can help you solve real-world problems, such as calculating pH in chemistry (which is a logarithmic scale), or understanding decibels in sound intensity, which also uses logarithmic measurements.

### Practice Problems
To further enhance your understanding, try practicing with these problems:
- Calculate \\( ext{log}_5(125) - ext{log}_5(25)\\).
- What is \\( ext{log}_3(81) - ext{log}_3(9)\\)?
