Answer:

387

Explanation:

To evaluate 3 - 6( Z - 2) ^3 at Z = -2, replace Z with -2:

3 - 6( -2 - 2) ^3

Simplify this result, obtaining 3 - 6( -4) ^3.

According to order of operations rules, exponentiation must be done first here, before multiplication and before subtraction. Therefore:

3 - 6( -4) ^3 → 3 - 6( -64). Again, these rules require that we multiply before subtracting:

3 - 6( -64) = 3 + 384, or 387
