Full solution

Q. X×X=64X \times X = 64
  1. Identify operation & equation: Identify the mathematical operation and equation.\newlineWe are given the equation X×X=64X\times X=64, which is a quadratic equation in the form of X2=64X^2=64.
  2. Solve quadratic equation: Solve the quadratic equation.\newlineTo find the value of XX, we take the square root of both sides of the equation X2=64X^2=64.\newlineX2=64\sqrt{X^2} = \sqrt{64}\newlineX=±8X = \pm8, because the square root of 6464 is 88 and the square of both positive and negative 88 is 6464.
