Answer 1

Punto 1
b) (3m)²-(2)(3m)(2n)+(2n)²=9m²-12mn+4n²
c) (1/3m²)²+(2)(1/3m²)(3n²)+(3n²)²=1/9m⁴+2m²n²+9n⁴

Punto 2
b) A=(x³+2y)²=4y²+4x³y+x⁶
c) A=(5x+3y)²=9y²+30xy+25x²

Punto 4
a)  (4x+5)(4x-5)=16x2−25
b)  (2m²-3n²)(2m²+3n²)=4m⁴−9n⁴
c)   (2mn³-3m²n)(2mn³+3m²n)=4m²n⁶−9m⁴n²
d)  (9/16)x⁴

Punto 5
a)  (ax+by)³=(ax)³+3(ax)²(by)+3(ax)(by)²+(by)³
b)  (3x²+2y³)³=(3x²)³+3(3x²)²(2y³)+3(3x²)(2y³)²+(2y³)³=27x⁶+54x⁴y³+36x²y⁶+8y⁹

c)  {(1/2)x³-(1/3)y⁴)³={(1/2)x³}³+3{(1/2)x³}²{(1/3)y⁴}+3(1/2)x³{(1/3)y⁴}²+{(1/3)y⁴}³=1/8x⁹+1/4x⁶y⁴+1/6x³y⁸+1/27y¹²

d)  {(a/b)+(2/3)y²}³={(a/b)³ + 3(a/b)²(2/3)y²+3(a/b){(2/3)y²}² + {(2/3)y²}³
= a³/b³+2a²y²/b²+4a/by⁴+8y⁶/27

Punto 6
a) x(x-y)²=xy²−2x²y+x³
b)  2x(2x+y)(2x-y)=8x³−2xy²

Punto 11
a) (2x+2y)(2x-2y)-(x-2)=4x²-4y²-x+2
b) (3x+2)(3x-2)/2=(9x²-4)/2

ESPERO ESTE BIEN Y TENGAS BUENA NOTA
