For B. its X^249=0 Simple and best practice solution for X^249=0 equation. Check how easy it is, and learn it for the future. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework. If it's not what You are looking for type in the equation solver your own equation and let us solve it. Equation: Solution for X^249=0 equation: Simplifying X2 + 49 = 0 Reorder the terms: 49 + X2 = 0 Solving 49 + X2 = 0 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '49' to each side of the equation. 49 + 49 + X2 = 0 + 49 Combine like terms: 49 + 49 = 0 0 + X2 = 0 + 49 X2 = 0 + 49 Combine like terms: 0 + 49 = 49 X2 = 49 Simplifying X2 = 49 Take the square root of each side: X = {7, 7}
