Math Problem Statement

Solve for x: (ln(x))^2 / 3 = y

Solution

The given equation is:

ln(x)23=y\frac{\ln(x)^2}{3} = y

To solve for xx, we can follow these steps:

Step 1: Multiply both sides by 3

ln(x)2=3y\ln(x)^2 = 3y

Step 2: Take the square root of both sides

ln(x)=±3y\ln(x) = \pm \sqrt{3y}

Step 3: Solve for xx by exponentiating both sides using the base ee

x=e±3yx = e^{\pm \sqrt{3y}}

Thus, the solution for xx is: x=e3yorx=e3yx = e^{\sqrt{3y}} \quad \text{or} \quad x = e^{-\sqrt{3y}}

Here are 5 related questions for further exploration:

  1. How does the solution change if the logarithmic base is not ee but another number?
  2. Can you explain why we take both positive and negative roots when solving?
  3. What are the properties of logarithmic and exponential functions used in this solution?
  4. How would you solve the equation if it involved a logarithm to a different base?
  5. What happens to the solution if yy is negative?

Tip: When working with logarithmic equations, always check for the domain of the logarithmic function (in this case, x>0x > 0).
