Math Problem Statement

Solve 0.52=e^-0.03x

Solution

To solve the equation 0.52=e0.03x0.52 = e^{-0.03x}, follow these steps:

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

ln(0.52)=ln(e0.03x)\ln(0.52) = \ln(e^{-0.03x}) Using the logarithmic property ln(ey)=y\ln(e^y) = y, we simplify the right-hand side: ln(0.52)=0.03x\ln(0.52) = -0.03x

Step 2: Solve for xx

x=ln(0.52)0.03x = \frac{\ln(0.52)}{-0.03}

Step 3: Calculate the logarithm and divide

ln(0.52)0.65393\ln(0.52) \approx -0.65393 x=0.653930.0321.80x = \frac{-0.65393}{-0.03} \approx 21.80

Thus, x21.80x \approx 21.80.
