Solving:

We know that 
Using formula and simplifying

So, we get 
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

First, add 8 to both sides


Now, divide both sides by 4


Take the exponents of both sides

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
