Answer 1

Vamos lá.

(2a + y)³

(2a + y).(2a + y).(2a + y)

8a³ + 12a²y + 6ay² + y³

Bons estudos

Answer 2

= (2a+y)^3
= (2a+y)^2 . (2a+y)
= (4a^2 + 2.2ay + y^2).(2a+y)
= (4a^2 + 4ay + y^2).(2a + y)
= 4a^2.2a + 4a^2.y + 4ay.2a + 4ay.y + y^2.2a + y^2. y

= 8a^3 + 4a^2y + 8a^2y + 4ay^2 + 2ay^2 + y^3

= 8a^3 + 12a^2 y + 6ay^2 + y^3
