(M+N) M=(3-5) 3=-2 3=-8
2. The sixth quartic formula shows that the sum of the times of the highest quartic term is 6, that is, 2+(m+2) = 6 and m = 2.
In addition, the monomial 2x (3n) y (5-m) z is also a sixth-order term, so
(3N)+(5-M)+ 1=6
3N+(5-2)+ 1=6
3N=2
N=2/3
Combined with the characteristics of mathematics, written expression ability refers to the correct writing of problem-solving s
