Question

Evaluate the following expression using the values given: Find x^3 - 2y^2 - 3x^3 + z^4 if x = 3, y = 5, and z = -3

Answer 1

So firstly, plug in the numbers into the expression:
`3^3-2*5^2-3*3^3+(-3)^4`

Next, solve the exponents:
`27-2*25-3*27+81`

Next, solve the multiplications:
`27-50-81+81`

Lastly, combine everything, and your answer will be -23.
