Introduction

Logarithmic expressions can be complex and challenging to simplify. However, with a clear understanding of the properties of logarithms, we can break down these expressions into manageable parts. In this article, we will explore how to simplify a logarithmic expression involving addition, subtraction, and multiplication of logarithms.

Understanding Logarithmic Properties

Before we dive into the problem, let's review some essential properties of logarithms:

  • Product Property: log⁑(ab)=log⁑a+log⁑b\log (ab) = \log a + \log b
  • Quotient Property: log⁑ab=log⁑aβˆ’log⁑b\log \frac{a}{b} = \log a - \log b
  • Power Property: log⁑ab=blog⁑a\log a^b = b \log a

These properties will be crucial in simplifying the given expression.

Breaking Down the Expression

The given expression is:

log⁑143+log⁑115βˆ’log⁑2215=log⁑\log \frac{14}{3} + \log \frac{11}{5} - \log \frac{22}{15} = \log

To simplify this expression, we will apply the properties of logarithms.

Step 1: Apply the Quotient Property

We can rewrite the first term using the quotient property:

log⁑143=log⁑14βˆ’log⁑3\log \frac{14}{3} = \log 14 - \log 3

Similarly, we can rewrite the second term:

log⁑115=log⁑11βˆ’log⁑5\log \frac{11}{5} = \log 11 - \log 5

The third term is already in the form of a quotient.

Step 2: Combine the Terms

Now, we can combine the terms using the product property:

log⁑14βˆ’log⁑3+log⁑11βˆ’log⁑5βˆ’log⁑2215\log 14 - \log 3 + \log 11 - \log 5 - \log \frac{22}{15}

Step 3: Simplify the Expression

We can simplify the expression by combining like terms:

We can rewrite the last term using the quotient property:

log⁑2215=log⁑22βˆ’log⁑15\log \frac{22}{15} = \log 22 - \log 15

Now, we can substitute this back into the expression:

log⁑14+log⁑11βˆ’log⁑3βˆ’log⁑5βˆ’log⁑22+log⁑15\log 14 + \log 11 - \log 3 - \log 5 - \log 22 + \log 15
