looks like someone is taking liberty with notation

Answer 4

yes, this is binomial coefficient of 4th degree \((x+y+z)^4\)

Answer 5

and I have the combination of degree like 4,0,0, for x^4 y^0z^0 and the coefficient of this element is defined by that formula

other element like x^2 yz will have the coefficient as \(\left(\begin{matrix}4\\2,1,1\end{matrix}\right)\)
