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 more manageable parts. In this article, we will explore the process of simplifying logarithmic expressions, focusing on the given expression logw(x26)4x2+83\log _w \frac{\left(x^2-6\right)^4}{\sqrt[3]{x^2+8}}. We will examine the properties of logarithms, apply the rules of logarithmic simplification, and compare the simplified expression with the given options.

Understanding Logarithmic Properties

Before diving into the simplification process, it is essential to understand the properties of logarithms. The logarithmic function is defined as:

logab=c    ac=b\log _a b = c \iff a^c = b

where aa is the base, bb is the argument, and cc is the exponent. The logarithmic function has several properties that are crucial for simplifying expressions:

  • Product Rule: loga(bc)=logab+logac\log _a (bc) = \log _a b + \log _a c
  • Quotient Rule: logabc=logablogac\log _a \frac{b}{c} = \log _a b - \log _a c
  • Power Rule: logabc=clogab\log _a b^c = c \log _a b

Simplifying the Given Expression

Now that we have a solid understanding of the properties of logarithms, let's apply these rules to simplify the given expression:

logw(x26)4x2+83\log _w \frac{\left(x^2-6\right)^4}{\sqrt[3]{x^2+8}}

Using the Quotient Rule, we can rewrite the expression as:

logw(x26)4logwx2+83\log _w \left(x^2-6\right)^4 - \log _w \sqrt[3]{x^2+8}

Next, we can apply the Power Rule to simplify the first term:

4logw(x26)logwx2+834 \log _w \left(x^2-6\right) - \log _w \sqrt[3]{x^2+8}

Now, let's focus on the second term. We can rewrite the cube root as a fractional exponent:

x2+83=(x2+8)13\sqrt[3]{x^2+8} = (x^2+8)^{\frac{1}{3}}

Using the Power Rule, we can rewrite the second term as:

13logw(x2+8)-\frac{1}{3} \log _w (x^2+8)

Combining the two terms, we get:

4logw(x26)13logw(x2+8)4 \log _w \left(x^2-6\right) - \frac{1}{3} \log _w (x^2+8)

Comparing with the Given Options

Now that we have simplified the expression, let's compare it with the given options:

A. 4logwx2129613logw(2x+8)4 \log _w \frac{x^2}{1296}-\frac{1}{3} \log _w(2 x+8)

B. 4logw(x26)3logw(x2+8)4 \log _w\left(x^2-6\right)-3 \log _w\left(x^2+8\right)

C. 4logw(x26)13logw(x2+8)4 \log _w\left(x^2-6\right)-\frac{1}{3} \log _w\left(x^2+8\right)

Based on our simplification, we can see that option C matches our result:

4logw(x26)13logw(x2+8)4 \log _w \left(x^2-6\right) - \frac{1}{3} \log _w (x^2+8)

Conclusion

In this article, we explored the process of simplifying logarithmic expressions using the properties of logarithms. We applied the Quotient Rule, Power Rule, and other logarithmic properties to simplify the given expression logw(x26)4x2+83\log _w \frac{\left(x^2-6\right)^4}{\sqrt[3]{x^2+8}}. Our simplified expression matched option C, which confirms the correct answer.
