Q. Consider the equation\newline0.3e3x=27 0.3 \cdot e^{3 x}=27 \text {. } \newlineSolve the equation for x x . Express the solution as a logarithm in basee.\newlinex= x= \newlineApproximate the value of x x . Round your answer to the nearest thousandth.\newlinex x \approx
  1. Isolate exponential term: Isolate the exponential term.\newlineTo solve for xx, we first need to isolate the exponential term e3xe^{3x}. We do this by dividing both sides of the equation by 0.30.3.\newlineCalculation: 0.3e3x=27e3x=270.3e3x=900.3\cdot e^{3x} = 27 \Rightarrow e^{3x} = \frac{27}{0.3} \Rightarrow e^{3x} = 90
  2. Take natural logarithm: Take the natural logarithm of both sides.\newlineTo solve for the exponent, we take the natural logarithm (ln\ln) of both sides of the equation because ln\ln and ee are inverse functions.\newlineCalculation: ln(e3x)=ln(90)\ln(e^{3x}) = \ln(90)
  3. Apply logarithm property: Apply the property of logarithms.\newlineUsing the property that ln(ey)=y\ln(e^y) = y, we can simplify the left side of the equation.\newlineCalculation: 3x=ln(90)3x = \ln(90)
  4. Solve for x: Solve for x.\newlineNow, we divide both sides of the equation by 33 to solve for xx.\newlineCalculation: x=ln(90)3x = \frac{\ln(90)}{3}
  5. Approximate x value: Approximate the value of xx. We use a calculator to find the numerical value of ln(90)\ln(90) and then divide by 33 to get the value of xx. Calculation: xln(90)/34.4998/31.4999x \approx \ln(90) / 3 \approx 4.4998 / 3 \approx 1.4999 Rounded to the nearest thousandth: x1.500x \approx 1.500
