Math Problem Statement

3ln x – 2 = 0 solve for exact answer

Solution

To solve the equation 3ln(x)2=03\ln(x) - 2 = 0 for xx, follow these steps:

  1. Isolate the logarithm: 3ln(x)=23\ln(x) = 2

  2. Divide both sides by 3: ln(x)=23\ln(x) = \frac{2}{3}

  3. Exponentiate both sides to get rid of the natural logarithm (since ln(x)\ln(x) is the natural logarithm, the base of the exponentiation is ee): x=e23x = e^{\frac{2}{3}}

So, the exact solution is: x=e23x = e^{\frac{2}{3}}

  2. What is the approximate value of e23e^{\frac{2}{3}}?
  3. Can you solve 5ln(x)=3ln(2)5\ln(x) = 3\ln(2)?
  4. How would you solve ln(x2)=4\ln(x^2) = 4?
  5. What happens if you take the logarithm of both sides of the equation x3=10x^3 = 10?

Tip: Remember that ln(x)\ln(x) is only defined for x>0x > 0, so when solving logarithmic equations, always check that your solutions are positive.
