Answer 2

Resposta:

D)5n E) x² F)6y³ G)3x³

Explicação

D)

$6n - 3n + 2n \\ (6 - 3 + 2)n \\ 8 - 3 = 5 \\ 5n$

E)

$x \times x \\ x {}^{1} \times x \\ x {}^{1 } \times x {}^{1} \\ x {}^{1 + 1} = x {}^{2}$

F)

$3y \times y \times 2y \\ 6y \times y \times y \\ 6y {}^{1} \times y \times y \\ 6y {}^{1} \times y {}^{1} \times y \\ 6y {}^{1} \times y {}^{1} \times y {}^{1} \\ 6y {}^{1 + 1 + 1} \\ 3 \times 1 = 3 \\ 6y {}^{3}$

G)

$6x {}^{2} \div 2x \\ 3x {}^{2} \times x \\ x {}^{2} \times x {}^{1} \\ 3x {}^{2 + 1} \\ 3x {}^{3}$
