1 answer

To evaluate the expression \( xy^2 - z \) for \( x = 6 \), \( y = -2 \), and \( z = -24.1 \), follow these steps:

  1. Calculate \( y^2 \): \[ y^2 = (-2)^2 = 4 \]

  2. Calculate \( xy^2 \): \[ xy^2 = 6 \times 4 = 24 \]

  3. Substitute the values into the expression \( xy^2 - z \): \[ xy^2 - z = 24 - (-24.1) \]

  4. Simplify the subtraction: \[ 24 - (-24.1) = 24 + 24.1 = 48.1 \]

Thus, the value of the expression is: \[ \boxed{48.1} \]
