Q. Evaluate 9y1−y09y^1-y^0 if y=−4y=-4
  1. Substitute y=−4y = -4: Step 11: Substitute y=−4y = -4 into the expression.\newlineCalculation: 9(−4)1−(−4)09(-4)^1 - (-4)^0\newline9(−4)−1=−36−1=−379(-4) - 1 = -36 - 1 = -37
  2. Simplify the expression: Step 22: Simplify the expression.\newlineCalculation: −36−1=−37-36 - 1 = -37
