Math Problem Statement

Solve. Round your answer to the nearest thousandth. 26=3^x x=

Solution

To solve the equation 26=3x26 = 3^x, we'll use logarithms. Here's the step-by-step process:

  1. Take the natural logarithm (ln) of both sides:

ln(26)=ln(3x)\ln(26) = \ln(3^x)

  1. Use the logarithmic property ln(ab)=bln(a)\ln(a^b) = b\ln(a):

ln(26)=xln(3)\ln(26) = x \ln(3)

  1. Solve for xx:

x=ln(26)ln(3)x = \frac{\ln(26)}{\ln(3)}

Now, calculate the values of the natural logarithms:

ln(26)3.258\ln(26) \approx 3.258 ln(3)1.099\ln(3) \approx 1.099

So:

x3.2581.0992.963x \approx \frac{3.258}{1.099} \approx 2.963

Final Answer:

x2.963x \approx 2.963
