Question

gente me ajuda por favor.

Answer 1

Resposta:

a)

$\frac{12 {a}^{3} {b}^{3} + 8a {b}^{2} }{2a {b}^{2} } = \\ \\ 6 {a}^{3 - 1} \times {b}^{3 - 2} + 4 {a}^{ 1 - 1} {b}^{2 - 2} = \\ \\ 6 {a}^{2} b + 4 {a}^{0} {b}^{0} = \\ \\ 6 {a}^{2} b + 4 \times 1 \times 1 = \\ \\ 6 {a}^{2} b + 4$

b)

$\frac{9 {x}^{2} {y}^{3} - 6 {x}^{3} {y}^{2} }{2 {x}^{2} y} = \\ \\ 4.5 {x}^{2 - 2} \times {y}^{3 - 1} - 3 {x}^{3 - 2} \times {y}^{2 - 1} = \\ \\ 4.5 {}^{} {y}^{2} - 3 {x}^{} {y}^{}$
