To solve the equation 5e^(3x) - 3 = 25 for x, we first add 3 to both sides of the equation to get: 5e^(3x) = 28 Next, we divide both sides by 5 to isolate e^(3x): e^(3x) = 28/5 To solve for x, we take the natural logarithm of both sides of the equation: ln(e^(3x)) = ln(28/5) Using the property of logarithms that ln(e^a) = a, we can simplify the left side of the equation: 3x = ln(28/5) Finally, we divide both sides by 3 to solve for x: x = (1/3)ln(28/5) Using a calculator, we can evaluate this expression to two decimal places: x ≈ 0.77 Therefore, the solution to the equation 5e^(3x) - 3 = 25 is x ≈ 0.77
