Answer 1

1) determine a parte literal e as coeficientes

a) 4×y² = xy^2
b) -ab3 = -ab
c) ײy = x^2y
d) -2m = m
e) 5ײy² = x^2y^2
f) -2a³b² = a^3b^2
g) ײyz = x ^2yz
h) -a²b²c² = -a^2b^2c^2

2) reduza os termos semelhantes

a) ×-5×+6×-7×-9×+12× = 8x
b) 2ab-5ab-8ab+7ab-ab = 2ab
c)׳-4ײ-5×+3-3׳+7ײ-4×+7 = -2x^3 -3x^2 -9x + 10
d)×⁴-4׳+2ײ-5×+3-×⁴+4׳-ײ+6×+-2 = ×^2 + x + 1
e) a²-2ab+b²-a²-2ab-b² = -4ab

3) determine o grau dos monômios
a) 4×yz = terceiro
b) -5a³b = quarto
c) 7m³p³q = sétimo
d)ײy³z⁴ = nono
5
e)-a²b²c= quinto
