Question

calcule:

obs: por favor gente :'(

a) 4x² y³/ 12 y⁴
b) 8x/ 19xy

Answer 1

$a) \: \frac{4 {x}^{2} {y}^{3} }{ 12{y}^{4} } \\ \\ \frac{4 {x}^{2} }{12} \times \frac{ {y}^{3} }{ {y}^{4} } \\ \\ \frac{ {x}^{2} }{3} \times {y}^{ - 1} \\ \\ \frac{ {x}^{2} }{3} \times \frac{1}{y} \\ \\ \frac{ {x}^{2} }{3y} \\ \\ \\ b) \: \frac{8x}{19xy} \\ \\ \frac{8}{19y} \times \frac{x}{x} \\ \\ \frac{8}{19y} \times 1 \\ \\ \frac{8}{19y}$
