Introduction

Logarithms are a fundamental concept in mathematics, and understanding their properties is crucial for solving various mathematical problems. In this article, we will focus on the properties of logarithms, specifically the mastery test on logarithmic expressions. We will analyze each expression and determine which ones are equivalent to the given expression.

The Given Expression

The given expression is log4(14x2)\log_4\left(\frac{1}{4} x^2\right). This expression involves a logarithm with base 4, and the argument of the logarithm is a fraction with x2x^2 in the numerator and 4 in the denominator.

Option A: 2log4(14)log4x22 \log_4\left(\frac{1}{4}\right) - \log_4 x^2

To determine if this expression is equivalent to the given expression, we need to apply the properties of logarithms. Specifically, we will use the property that states loga(bc)=clogab\log_a (b^c) = c \log_a b. We will also use the property that states logabc=logablogac\log_a \frac{b}{c} = \log_a b - \log_a c.

Applying the first property, we can rewrite x2x^2 as x2log4xx^{2 \log_4 x}. However, this is not the correct application of the property. The correct application is to use the property that states loga(bc)=logab+logac\log_a (b \cdot c) = \log_a b + \log_a c. We can rewrite 14x2\frac{1}{4} x^2 as 14x2\frac{1}{4} \cdot x^2, and then apply the property to get log414+log4x2\log_4 \frac{1}{4} + \log_4 x^2.

However, we are not done yet. We need to apply the property that states loga1b=logab\log_a \frac{1}{b} = -\log_a b. We can rewrite log414\log_4 \frac{1}{4} as log44-\log_4 4. Since logaa=1\log_a a = 1, we can rewrite log44-\log_4 4 as 1-1. Therefore, we have 1+log4x2-1 + \log_4 x^2.

Now, we need to apply the property that states loga(bc)=clogab\log_a (b^c) = c \log_a b. We can rewrite x2x^2 as x2log4xx^{2 \log_4 x}. However, this is not the correct application of the property. The correct application is to use the property that states loga(bc)=logab+logac\log_a (b \cdot c) = \log_a b + \log_a c. We can rewrite x2x^2 as xxx \cdot x, and then apply the property to get log4x+log4x\log_4 x + \log_4 x.

Therefore, we have 1+2log4x-1 + 2 \log_4 x. However, this is not the correct expression. We need to apply the property that states logabc=logablogac\log_a \frac{b}{c} = \log_a b - \log_a c. We can rewrite log4x2\log_4 x^2 as log4xlog4x\log_4 x - \log_4 x. Therefore, we have 1+2log4xlog4x-1 + 2 \log_4 x - \log_4 x. Simplifying, we get 1+log4x-1 + \log_4 x.

However, this is still not the correct expression. We need to apply the property that states loga(bc)=logab+logac\log_a (b \cdot c) = \log_a b + \log_a c. We can rewrite x2x^2 as xxx \cdot x, and then apply the property to get log4x+log4x\log_4 x + \log_4 x. Therefore, we have 1+2log4x-1 + 2 \log_4 x. However, this is still not the correct expression.
