Q. Determine the value of y y , if x x is 5757 .\newliney=x−21 y=\sqrt{x-21} \newlineAnswer: y= y=
  1. Substitute xx with 5757: To find the value of yy, we need to substitute xx with 5757 in the equation y=x−21y = \sqrt{x - 21}.\newliney=57−21y = \sqrt{57 - 21}
  2. Perform subtraction: Now, we perform the subtraction inside the square root. \newliney=36y = \sqrt{36}
  3. Find square root: Next, we find the square root of 3636.\newliney=6y = 6
