Question

1.-EFECTUAR:(2x+1)(4x)-8x(x+1)



2.-EFECTUAR:(-8x²y⁴)(-2x³y)(-6x⁴y²)

Answer 1

Explicación paso a paso:

$(2x + 1)(4x) - 8x(x + 1) \\ 8 {x}^{2} + 4x - 8 {x}^{2} - 8x \\ 0 {x}^{2} - 4x = \: - 4x$

$( - 8 {x}^{2} {y}^{4} )( - 2 {x}^{3} y)( - 6 {x}^{4} {y}^{2} ) \\ - 8 {x}^{2} {y}^{4 } \times( - 2 {x}^{3} y) \times ( - 6 {x}^{4} {y}^{2} ) \\ resultado \: - 96 {x}^{9} {y}^{7}$
