D.- (1/2 m3 - 2/3m2) + (-2/5m3 + 1/6m2)
E.- (-6x3y2+7x2y3-9) + (-8/3x3y2 + 7/4)
F.- (8a2b4 - 2/7a4b3) + (-5a4b3 - 1/3a3b4)

Answer 1

Respuesta:

$10 - ( - 56) - ( - 27)$

$10a {}^{2} - 5ab + 5b$

$- 44mn - 11m + 3$

$- 8 \gamma m ^{3}$

$- 18y {}^{2} </p><p>+ 14y {}^{3} - 9 - 72 \gamma xy {}^{2} + 7 \gamma {}^{4}$

$16ab {}^{4} - 56 \gamma ab {}^{3} - 9 \gamma ab {}^{4}$
