Answer 1

Answer:

your answer is z3+27+9z2+27z

Answer 2

Answer:

(z³ + 9z² + 27z + 27)

Step-by-step explanation:

(z + 3)³

= (z + 3)² (z + 3)

= (z² + 6z + 9) (z + 3)

= (z³ + 6z² + 9z + 3z² + 18z + 27)

= (z³ + 9z² + 27z + 27)

I think this is the answer, using the simplest way.

Hope this helped. :D
