a) (4+1)
b) (2-y)?
c) (3x +2y2)3
d) (4x2 + 4w3)
3 - Complete os espaces:​

Answer 1

Resposta:

a)25

b)4-4y+y²

c)27x³+54x²y²+36xy⁴+8y⁶

d)64x⁶+192x⁴w³+192x²w⁶+64w⁹

Explicação passo-a-passo:

a) (4+1)²

  5²=25

b) (2-y)²

2²-2.2.y+y²=

4-4y+y²

c) (3x+2y²)³

(3x)3+3.(3x)².(2y²)+3.(3x).(2y²)²+(2y²)³=

27x³+54x²y²+36xy⁴+8y⁶

d)(4x²+4w³)³

(4x²)³+3(4x²)².(4w³)+3.(4x²).(4w³)²+(4w³)³=

64x⁶+192x⁴w³+192x²w⁶+64w⁹
