Resposta:
Vamos resolver as questões passo a passo:
a) (-28a⁴b) ÷ (4a⁵b⁶)
= -7/a b⁵
b) (36mn²) ÷ (-6m⁴nz)
= -6n/m³z
c) (-81a⁷bc³d) ÷ (-9abcd)
= 9a⁶c²d²
d) (+625xyz⁴) ÷ (-5x³y)
= -125xz³
e) (3/4 x⁴y) ÷ (12x⁶y)
= 1/16x²
f) (5/25 a⁴bc⁶) ÷ (+4/4 a²b⁷c)
= 5/100a²/b
g) (-2m⁴n) × (8/4 mn³) × (5mn)
= -40m⁶n⁵
Espero ter ajudado! Se tiver mais alguma dúvida, é só me perguntar.
