What is the value of xyz

if x=1, y=2, z=−1
(

Given that x = 1, y = 2, and z = -1, the value of xyz is:

xyz = 1 * 2 * (-1) = -2

To find the value of xyz when x=1, y=2, z=-1, we simply need to multiply the values together.

xyz = x * y * z

Substituting the given values:

xyz = 1 * 2 * (-1)

Multiplying:

xyz = -2
