Ответ:

$- 0.64$

Пошаговое объяснение:

$2 {x}^{3} y - 12 {x}^{2} {y}^{2} + 24x {y}^{3} - 16 {y}^{4} = 2y {(x - 2y)}^{3}$

$2y {(x - 2y)}^{3} = 2 \cdot ( - 0.04) \cdot {(1.92 - 2 \cdot ( - 0.04))}^{3} = 2 \cdot ( - 0.04) \cdot {2}^{3} = - 0.04 \cdot {2}^{4} = - 0.04 \cdot 16 = - 0.64$

-0,64

Пошаговое объяснение:

2x^3 •y-12x^2 •y^2 +24xy^3 -16y^4=2y(x^3 -6x^2 •y+12xy^2 -8y^3)=2y((x-2y)(x^2 +2xy+4y^2)-6xy(x-2y))=2y(x-2y)(x^2 +2xy+4y^2 -6xy)=2y(x-2y)(x^2-4xy+4y^2)=2y(x-2y)(x-2y)^2=2y(x-2y)^3=2•(-0,04)(1,92-2•(-0,04))^3=-0,08•(1,92+0,08)^3=-0,08•2^3=-8/100 •8=-64/100=-0,64
