Introduction

In mathematics, solving logarithmic equations is a crucial aspect of algebra and calculus. The equation $2 \ln x = 4 \ln 2$ is a simple yet interesting example of a logarithmic equation that can be solved using various methods. In this article, we will explore the potential solutions to this equation and list them from least to greatest.

Understanding the Equation

The given equation is $2 \ln x = 4 \ln 2$. To solve this equation, we need to understand the properties of logarithms. The logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In this case, the base is $e$ (Euler's number), and the logarithm is natural logarithm.

Using Properties of Logarithms

To solve the equation, we can use the property of logarithms that states $\log_a b^c = c \log_a b$. Applying this property to the given equation, we get:

$$2 \ln x = 4 \ln 2$$

$$\ln x^2 = 4 \ln 2$$

Exponentiating Both Sides

To eliminate the logarithm, we can exponentiate both sides of the equation. Since the base of the logarithm is $e$, we can use the exponential function $e^x$ to eliminate the logarithm:

$$e^{\ln x^2} = e^{4 \ln 2}$$

$$x^2 = e^{4 \ln 2}$$

Simplifying the Right-Hand Side

To simplify the right-hand side of the equation, we can use the property of exponents that states $e^{ab} = (e^a)^b$. Applying this property, we get:

$$x^2 = (e^{\ln 2})^4$$

$$x^2 = 2^4$$

Solving for x

To solve for $x$, we can take the square root of both sides of the equation:

$$x = \pm \sqrt{2^4}$$

$$x = \pm 4$$

Listing the Potential Solutions

The potential solutions to the equation $2 \ln x = 4 \ln 2$ are $x = 4$ and $x = -4$. However, we need to consider the domain of the natural logarithm function, which is all positive real numbers. Therefore, the only valid solution is $x = 4$.

Conclusion

In conclusion, the potential solutions to the equation $2 \ln x = 4 \ln 2$ are $x = 4$ and $x = -4$. However, the only valid solution is $x = 4$ due to the domain of the natural logarithm function.

Additional Solutions

In addition to the solution $x = 4$, we can also consider the solution $x = 0$. However, this solution is not valid because the natural logarithm function is undefined at $x = 0$.

Alternative Solutions

Another way to solve the equation is to use the property of logarithms that states $\log_a b = \frac{\ln b}{\ln a}$. Applying this property, we get:

$$2 \ln x = 4 \ln 2$$

$$\ln x = 2 \ln 2$$

$$\ln x = \ln 2^2$$

$$\ln x = \ln 4$$

$$x = 4$$

Conclusion

In conclusion, the potential solutions to the equation $2 \ln x = 4 \ln 2$ are $x = 4$ and $x = -4$. However, the only valid solution is $x = 4$ due to the domain of the natural logarithm function.
