Math Problem Statement
Solve for x: ln(x) - ln(4) = 0
Solution
The equation provided is:
To solve for :
Step 1: Simplify the equation
Using the logarithmic property , the equation becomes:
Step 2: Exponentiate to eliminate the logarithm
Exponentiate both sides of the equation with base : Since :
Step 3: Solve for
Multiply both sides by 4:
Final Answer:
Would you like me to explain any step in more detail or provide additional related problems to practice? Here are some related questions to expand your understanding:
- What is the general property of logarithms for subtraction, and how does it apply to different bases?
- How would the solution change if the equation were for some arbitrary ?
- Can logarithmic equations like this have no solution or multiple solutions? Why or why not?
- How would you graph and verify the solution visually?
- What happens if you replace with (logarithm base 10) in the equation?
Tip: Always check the domain of the logarithmic functions to ensure the arguments are valid (positive numbers).
