Question

efetue e simplifique​

Answer 1

Resposta:

Explicação passo-a-passo:

a)                                    

  $\frac{1}{4}y^{2} .10-\frac{1}{4}.y^{2} \\\\\frac{1}{2}y^{2}.5-\frac{1}{4}y^{3} \\\frac{5}{2}y^{2} -\frac{1}{4} y^{3}$

b)

$-\frac{2t-8}{z} \\\\\frac{8-2t}{z}$

c)

$-5m.(-12)-5m. (-\frac {4}{5})\\60m+m.4m\\60m+4m^{2}$

d)

$\frac{x}{6}. \frac{x-12x^{2}+24 }{2}\\ \\\frac{x.(x-12x^{2}+24) }{12} \\\\frac{x^{2}-12x^{3}+24x }{12} \\\\\\frac{-12x^{3+x^{2}+24x } }{12}$
