(6k-8m)2

(x+2y)6

(3x+2y)(3x-2y)

(7/4x-5)(7/4x-1)

(4x3-8y2)3

Answer 1

(6k-8m)²= (6k)² - 2(6K)(8m) + (8m)²=36k² - 96km + 64m²

(x+2y)6= x6+12x5y+60x4y2+160x3y3+240x2y4+192xy5+64y6

(3x+2y)(3x-2y)= 9x² - 4y²

(7/4x - 5)(7/4x - 1)= $\frac{49}{(4x - 5) (4x-1)}$

(4x³ - 8y²)³= 64x9 - 384 x6y²+768 x³y4 - 512y6

espero que sirve la respuestas.  :)
