The calculated value of the expression is 5 for the given values of x, y and z
How to evaluate the expression for the given values of x, y and z
From the question, we have the following parameters that can be used in our computation:
x = 3
y = -3
z = 5
Also, we have
z - 3xy² - xz³
Substitute the known values into the equation
z - 3xy² - xz³ = 5 - 3 * 3 * (-3)² - 3 * (-3)³
Evaluate
z - 3xy² - xz³ = 5
Hence, the value of the expression is 5
Question
