Question

O VALOR DA EXPRESSÃO....

Answer 1

$\frac{ \frac{9 {x}^{4} {y}^{2} }{ {a}^{6} {b}^{6} } }{ \frac{9 {x}^{3} {y}^{6} }{4 {a}^{6} {b}^{6} } } = \frac{9 {x}^{4} {y}^{2} }{ {a}^{6} {b}^{6}} \times \frac{4 {a}^{6} {b}^{6} }{9 {x}^{3} {y}^{6}} = \frac{36 {a}^{6} {b}^{6} {x}^{4} {y}^{2} }{9 {a}^{6} {b}^{6} {x}^{3} {y}^{6} } = \frac{4x}{ {y}^{4} }$
