Answer:
-216z²
Step-by-step explanation:
Okey dokey so this is actually a pretty simple problem.
You just need to multiply everything out starting with like terms.
(-6)·(-6)·(-6)·z·z
36·(-6)·z·z
-216·z·z
[multiply the z's now]
-216·z²
[you can multiply a number and a variable so lets do that :)]
-216z²
