Solve the equation \(\ln(1 + 2^x) = 2\), giving your answer correct to 3 decimal places.
Solution
To solve the equation \(\ln(1 + 2^x) = 2\), we first remove the logarithm by exponentiating both sides:
\(1 + 2^x = e^2\).
Next, solve for \(2^x\):
\(2^x = e^2 - 1\).
Now, take the logarithm base 2 of both sides to solve for \(x\):
\(x = \log_2(e^2 - 1)\).
Using a calculator, we find:
\(x \approx 2.676\).
