Math Problem Statement

Solve for xx: 3x=323x=32

x=x=   

Enter solution using logs

Solution

To solve the equation 3x=323^x = 32 using logarithms, follow these steps:

  1. Start with the equation: 3x=323^x = 32

  2. Take the natural logarithm (ln\ln) of both sides: ln(3x)=ln(32)\ln(3^x) = \ln(32)

  3. Use the logarithmic power rule (ln(ab)=bln(a)\ln(a^b) = b \ln(a)): xln(3)=ln(32)x \ln(3) = \ln(32)

  4. Solve for xx: x=ln(32)ln(3)x = \frac{\ln(32)}{\ln(3)}

  5. Compute the logarithms (if numerical evaluation is required): xln(32)ln(3)3.46571.09863.15x \approx \frac{\ln(32)}{\ln(3)} \approx \frac{3.4657}{1.0986} \approx 3.15

Thus, the solution is: x=ln(32)ln(3)or approximately x3.15x = \frac{\ln(32)}{\ln(3)} \quad \text{or approximately } x \approx 3.15
