Introduction

Exponential equations are a fundamental concept in mathematics, and solving them requires a deep understanding of logarithmic functions. In this article, we will explore the logarithmic form of the exponential equation $3^7 = (4x + 3)$. We will examine the different options and determine the correct logarithmic form.

Understanding Exponential Equations

Exponential equations involve a base raised to a power, and the result is equal to a specific value. In the given equation, $3^7 = (4x + 3)$, the base is 3, and the power is 7. The result is equal to $4x + 3$.

Logarithmic Form

To solve exponential equations, we can use logarithmic form. The logarithmic form of an exponential equation is written as $\log_b a = c$, where $b$ is the base, $a$ is the result, and $c$ is the power.

Option A: log73=(4x+3)\log_7 3 = (4x + 3)

Option A is incorrect because the base of the logarithm is 7, but the result is $4x + 3$, not 3. The correct logarithmic form should have the base as the result, not the other way around.

Option B: log7(4x+3)=3\log_7(4x + 3) = 3

Option B is also incorrect because the power of the logarithm is 3, but the result of the exponential equation is $4x + 3$, not 7. The correct logarithmic form should have the base as the result, not the other way around.

Option C: log37=(4x+3)\log_3 7 = (4x + 3)

Option C is incorrect because the base of the logarithm is 3, but the result is $4x + 3$, not 7. The correct logarithmic form should have the base as the result, not the other way around.

Option D: log3(4x+3)=7\log_3(4x + 3) = 7

Option D is the correct logarithmic form of the exponential equation $3^7 = (4x + 3)$. The base of the logarithm is 3, the result is $4x + 3$, and the power is 7.

Conclusion

In conclusion, the correct logarithmic form of the exponential equation $3^7 = (4x + 3)$ is $\log_3(4x + 3) = 7$. This is because the base of the logarithm is 3, the result is $4x + 3$, and the power is 7.

Step-by-Step Solution

To solve the exponential equation $3^7 = (4x + 3)$, we can use the following steps:

  1. Write the equation in logarithmic form: $\log_3(4x + 3) = 7$
  2. Use the definition of logarithms to rewrite the equation: $3^7 = 4x + 3$
  3. Solve for $x$: $4x = 3^7 - 3$
  4. Simplify the: $4x = 2187 - 3$
  5. Solve for $x$: $4x = 2184$
  6. Divide both sides by 4: $x = \frac{2184}{4}$
  7. Simplify the equation: $x = 546$

Final Answer

The final answer is $\boxed{546}$.
