Answer 1

500 - {5 + 10 x [20: 5 - 2 + 4x ( 5+ 2 x 3)] } =​  ¿?

Vamos a simplificar paso a paso.

$500-(5+10x(\frac{20}{5} -2+4x(5+2x(3))))$

Distribuir el signo negativo:

$=500+-1(5+10x(\frac{20}{5} -2+4x(5+2x(3))))$

$=500+(-1)(5)+-1(10x(\frac{20}{5} -2+4x(5+2x(3))))$

$=500+-5+-240x^3-200x^2-20x$

Distribuye:

$=500+-5+-240x^3+-200x^2+-20x$

Combinar términos comunes:

$=500+-5+-240x^3+-200x^2+-20x$

$=(-240x^3)+(-200x^2)+(-20x)+(500+-5)$

$=-240x^3+-200x^2+-20x+495$

Solución:

$=-240x3-200x2-20x+495$
