$$

Introduction

In mathematics, logarithmic functions play a crucial role in various mathematical operations. The expression $3x \log 2$ involves a logarithmic function and a constant multiplier. In this article, we will delve into the world of logarithms and explore how to calculate this expression.

Understanding Logarithms

A logarithm is the inverse operation of exponentiation. It is a mathematical function that takes a number as input and returns the power to which another fixed number, the base, must be raised to produce that number. In other words, if $y = \log_b x$, then $b^y = x$. The logarithm of a number to a certain base is the exponent to which the base must be raised to produce that number.

The Properties of Logarithms

Logarithms have several important properties that make them useful in mathematical calculations. Some of the key properties of logarithms include:

• Product Rule: $\log_b (xy) = \log_b x + \log_b y$
• Quotient Rule: $\log_b \left(\frac{x}{y}\right) = \log_b x - \log_b y$
• Power Rule: $\log_b (x^y) = y \log_b x$

Calculating the Expression: $3x \log 2$

Now that we have a basic understanding of logarithms and their properties, let's focus on calculating the expression $3x \log 2$. To do this, we need to apply the properties of logarithms.

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

$$3x \log 2 = 3x \cdot \log 2$$

Since the constant $3$ is outside the logarithm, we can use the Product Rule to rewrite the expression as:

$$3x \log 2 = 3 \log 2 + x \log 2$$

Now, we can see that the expression is a sum of two logarithmic terms. We can use the Product Rule again to rewrite the expression as:

$$3x \log 2 = \log 2^3 + \log 2^x$$

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

$$3x \log 2 = 3 \log 2 + x \log 2$$

Now, we can see that the expression is a sum of two logarithmic terms. We can use the Product Rule again to rewrite the expression as:

$$3x \log 2 = \log 2^3 + \log 2^x$$

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

$$3x \log 2 = \log (2^3 \cdot 2^x)$$

Simplifying the expression, we get:

$$3x \log 2 = \log (2^{3+x})$$

In this article, we have explored the expression $3x \log 2$ and calculated its value using the properties of logarithms. We have seen how to apply the Power Rule, Product Rule, and Quotient Rule to rewrite the expression in a simpler form.
