Q. Consider the equation 9e2z=549 \cdot e^{2 z}=54 .\newlineSolve the equation for z z . Express the solution as a logarithm in base-e e .\newlinez=z = \square \newlineApproximate the value of z z . Round your answer to the nearest thousandth.\newlinezz \approx \square
  1. Divide by 99: Divide both sides of the equation by 99 to isolate the exponential term.\newline9e2z=549e^{2z} = 54\newlinee2z=549e^{2z} = \frac{54}{9}\newlinee2z=6e^{2z} = 6
  2. Take ln of both sides: Take the natural logarithm (logarithm base ee, denoted as ln) of both sides to solve for 2z2z.\newlineln(e2z)=ln(6)\ln(e^{2z}) = \ln(6)
  3. Simplify using property: Use the property of logarithms that ln(ex)=x\ln(e^x) = x to simplify the left side of the equation.2z=ln(6)2z = \ln(6)
  4. Divide by 22: Divide both sides by 22 to solve for zz.z=ln(6)2z = \frac{\ln(6)}{2}
  5. Approximate value: Use a calculator to approximate the value of zz to the nearest thousandth.\newlinezln(6)2z \approx \frac{\ln(6)}{2}\newlinez0.8952z \approx \frac{0.895}{2}\newlinez0.448z \approx 0.448
