Question

If x, y, and z are all positive, evaluate x² + y² + z².

Answer 1

To evaluate x² + y² + z², plug in the values of x, y, and z. For example, if x = 2, y = 3, and z = 4, then x² + y² + z² = 29.

Step-by-step explanation:

To evaluate x² + y² + z², we need to know the values of x, y, and z. Let's assume x = 2, y = 3, and z = 4. Plugging these values into the expression, we get:

x² + y² + z² = (2)² + (3)² + (4)² = 4 + 9 + 16 = 29.

So, when x = 2, y = 3, and z = 4, the value of x² + y² + z² is 29.
