Chapter 5: Q 101. (page 299)

Solve the equation.
$e^{2 x + 5} = 8$

Short Answer

Expert verified

The solution to the equation, $e^{2 x + 5} = 8$ is, $x = \frac{1}{2} (\ln 8 - 5)$ .

Step by step solution

Step 1. Given Information

The given equation to be solved is $e^{2 x + 5} = 8$ .

Step 2. Formula used

Natural logarithm:

$\ln e = 1$

Step 3. Finding Solution

The given equation is $e^{2 x + 5} = 8$ .

Take logarithm on both sides.

$e^{2 x + 5} = \ln 8 (2 x + 5) \ln e = \ln 8 2 x + 5 = \ln 8 2 x = \ln 8 - 5 x = \frac{1}{2} (\ln 8 - 5)$

The solution to the given equationis, $x = \frac{1}{2} (\ln 8 - 5)$ .
