Answer 2

Oie, Td Bom?!

$= (3x + 2y {}^{2} ) {}^{3}$

$= (3x) {}^{3} + 3 \: . \: (3x) {}^{2} \: . \: 2y {}^{2} + 3 \: . \: 3x \: . \: (2y {}^{2} ) {}^{2} + (2y {}^{2} ) {}^{3}$

$= 27x {}^{3} + 3 \: . \: 9x {}^{2} \: . \: 2y {}^{2} + 3 \: . \: 3x \: . \: 4y {}^{4} + 8y {}^{6}$

$= 27x {}^{3} + 54x {}^{2} y {}^{2} + 36xy {}^{4} + 8y {}^{6}$
