Select the correct answer. what is the approximate solution to this equation? a. b. c. d.

Diano4ka-milaya [45]

The approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4

<h3>Solving equations</h3>

From the question, we are to determine the approximate solution to the given equation,

The given equation is

$4lnx -8 =12$

First, add 8 to both sides

$4lnx -8+8 =12+8$

$4lnx =20$

Now, divide both sides by 4

$ln x =\frac{20}{4}$

$ln x = 5$

Take the exponents of both sides

$e^{lnx} = e^{5}$

x = 148.413

x ≅ 148.4

Hence, the approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4
