Full solution

Q. Determine the value of y y , if x x is 1616 .\newliney=x4 y=\sqrt{x}-4 \newlineAnswer: y= y=
  1. Substitute xx value: Substitute the value of xx into the equation.\newlineWe are given that x=16x = 16, and we need to find the value of yy from the equation y=x4y = \sqrt{x} - 4.\newlineSubstitute xx with 1616: y=164y = \sqrt{16} - 4.
  2. Calculate square root: Calculate the square root of 1616. The square root of 1616 is 44, since 4×4=164 \times 4 = 16. So, y=44y = 4 - 4.
  3. Subtract to find yy: Subtract 44 from 44 to find the value of yy. Perform the subtraction: y=44=0y = 4 - 4 = 0.
