a) M= (6x⁶y- 5x⁶y) +(\(\dfrac{1}{3}\)x⁴y³- 4x⁴y³) -( y⁷-2y⁷) +(10-2,5)

= x⁶y - \(\dfrac{11}{3}\)x⁴y³+y⁷+7,5

bậc: 7

b) Thay x=-1; y=1 vào biểu thức M, ta được:

M=(-1)⁶.1 - \(\dfrac{11}{3}\).(-1)⁴.1³ + 1⁷ +2,5

= 1 - \(\dfrac{11}{3}\) + 1 +\(\dfrac{5}{2}\)

= \(\dfrac{5}{6}\)

Vậy giá trị của biểu thức M là \(\dfrac{5}{6}\)
