1) (1+m²)²
2) (5x²+xy)²

Answer 1

1) (1+m²)²

1 + 2m^2 + m^4
=============================
2) (5x²+xy)²

25x^4 + 10x^2.xy + x^2y^2

25x^4 + 10x^3.y + x^2y^2

Answer 2

Boa  noite,primeiramente:
1) (1 +m²)² => 1² + 2.1.m² + (m²)²
=> m^4 + 2m² + 1

2)(5x² + xy)²  +> (5x²)² + 2.5x².xy +(xy)²
=> 5x^4 + 10x³y +x²y²
