Question

Evaluate the expression if x=1, y=3, and z=4.
3y³ - ( z - x² )

Answer 1

To evaluate the expression 4.3y³ - (z - x²) when x=1, y=3, and z=4, substitute the given values and simplify the expression to obtain the result 113.1.

Step-by-step explanation:

To evaluate the expression 4.3y³ - (z - x²) when x=1, y=3, and z=4, we substitute the given values into the expression:

1. Replace x with 1: 4.3(3)³ - (4 - 1²)
2. Simplify the exponents: 4.3(27) - (4 - 1)
3. Multiply and subtract: 116.1 - 3
4. Final result: 113.1
