Answer 1

Resposta:

a)6x4y3

Explicação passo-a-passo:

12x3y2÷2xy=

6x2y2x1y1

6x4y2+1

6x4y3

Answer 2

Resposta:

A)

$12x^{3} y^{2} / 2xy = \\\\12x^{2} y = \\\\12x^{2} = -y\\\\x^{2} = \frac{-y}{12} \\\\x = \sqrt{\frac{-y}{12} }$

B)

$(-3ab^{3} ) / (-ab^{2} ) =\\\\+3a^{-2} b= \\\\3a^{-2} = -b\\\\a^{-2} = \frac{-b}{3}$
