Question

Efetue as divisões.Alguem me ajuda???por favvorr
$a)(8x {}^{4} y {}^{2} - x {}^{2} y {}^{2}) \div ( - 5x {}^{2}y)$
$b)(22abc {}^{2} + \frac{1}{2}bc) \div 11bc$

​

Answer 1

Resposta:

A)

$\dfrac{8x^4y^2 - x^2y^2}{-5x^2y} \\ \\ \\ Corta~as~incognitas~com~~ incognitas\\ \\ \\ \dfrac{8x^2~~^\not 2.y^\not 2 - \not x^\not 2 y^\not 2}{-5\not x^\not 2 \noty} \\ \\ \\ =>-\dfrac{8x^2y-y}{5}$

===

B)

$\dfrac{22abc + \dfrac{1}{2}bc }{11bc} \\ \\ \\ \dfrac{22abc + \dfrac{bc}{2}}{11bc}\\ \\ \\ \dfrac{ \dfrac{44abc +bc}{2}}{11bc}\\ \\ \\ O~2~que~esta~dividindo,~passa~multiplicado$

$\dfrac{44abc +bc}{11bc . 2} \\ \\ \\ \dfrac{44abc +bc}{22bc}\\ \\ \\\dfrac{44a\not b\not c +\not b \notc}{22 \notb \notc}\\ \\ \\=>\dfrac{44a + 1}{22}$
