Question

11. efetue as operaçoes proposta: a) + 3xy -(-xy) + xy+ b) + 15x - (-3x)-(+7x)+(-2x)= c)(+5x).(-4x2)= d)(-9x2y).(-5xy2)= e)(-x3).(5yx2).(-2y3)= f)15x6 : 3x2 = g)(-30x5) : (+3x3)=

Answer 1

Resposta:

a) 5xy

b) 9x

c) -20x³

d) 45x³y³

e) 10x⁵y⁴

f) 5x⁸

g) -10⁸

Explicação passo-a-passo:

a) 3xy + xy + xy = 5xy

b) 15x + 3x - 7x - 2x = 18x - 9x = 9x

c) (5x).(-4x²) = -20x³

d) 45x³y³

e) (-5x⁵y)(-2y³) = 10x⁵y⁴

f) (15x÷3x)⁶⁺² = 5x⁸

g)(-30x÷3x)⁵⁺³ = -10⁸
