Math Problem Statement

5+ln(-3x)=2 what is x

Solution

To solve the equation 5+ln(3x)=25 + \ln(-3x) = 2 for xx, we follow these steps:

  1. Subtract 5 from both sides of the equation: ln(3x)=25\ln(-3x) = 2 - 5 ln(3x)=3\ln(-3x) = -3

  2. Exponentiate both sides to remove the natural logarithm: 3x=e3-3x = e^{-3}

  3. Solve for xx: x=e33x = -\frac{e^{-3}}{3} x=13e3x = -\frac{1}{3e^3}

Thus, the solution is: x=13e3x = -\frac{1}{3e^3}

  3. How does exponentiation help in solving logarithmic equations?
  4. What are some common mistakes when solving logarithmic equations?
  5. Can you solve an equation involving both logarithms and exponents?

Tip: When solving logarithmic equations, always check if the argument of the logarithm is positive, as the logarithm of a non-positive number is undefined in the real number system.
