Question

Solve the exponential equation for x. A. x = 4 B. x = -4 C. x = 2 D. x = -2

Answer 1

x = 338.7

Explanation:

Equation: 256 = (1/4)3x + 2

Step 1: Distribute

256 = (1/4)3x + 2

256 = 3/4x + 2

Step 2: Subtract 2 from both sides

256 - 2 = 3/4x + 2 - 2

254 = 3/4x

Step 3: Multiply both sides by 4/3

254 * 4/3 = 3/4x * 4/3

338.7 = x

Answer: x = 338.7
