Question

al desarrokar (x²- 3y)³ se obtiene?​

Answer 1

Respuesta:

$\left(x^{2} -\:3y\right)^{3}$

$=\left(x^2\right)^3-3\left(x^2\right)^2\cdot \:3y+3x^2\left(3y\right)^2-\left(3y\right)^3$

$=x^6-9x^4y+27x^2y^2-27y^3$

Answer 2

Respuesta:

$({ {x}^{2} })^{3} - 3 \times { ({x}^{2} )}^{2} \times 3y + 3 {x}^{2} \times ({3y})^{2} - ( {3y})^{3} \\ {x}^{6} - 3 {x}^{4} \times 3y + 3 {x}^{2} \times 9 {y}^{2} - 27 {y}^{3} \\ {x}^{6} - 9 {x}^{4} y + 27 {x}^{2} {y}^{2} - 27 {y}^{3}$
