Chapter 5: Q 102. (page 299)

Solve the equation.
$e^{- 2 x + 1} = 13$

Short Answer

Expert verified

The solution to the equation, $e^{- 2 x + 1} = 13$ is, $x = \frac{1}{2} (1 - \ln 13)$ .

Step by step solution

Step 1. Given Information

The given equation to be solved is $e^{- 2 x + 1} = 13$ .

Step 2. Formula used

Natural logarithm:

$\ln e = 1$

Step 3. Finding Solution

The given equation is $e^{- 2 x + 1} = 13$ .

Take logarithm on both sides.
$\ln e^{- 2 x + 1} = \ln 13 (- 2 x + 1) \ln e = \ln 13 - 2 x + 1 = \ln 13 - 2 x = \ln 13 - 1 x = \frac{1}{2} (1 - \ln 13)$

The solution to the given equationis, $x = \frac{1}{2} (1 - \ln 13)$ .
