Answer:
x = 0
x = 3
Step-by-step explanation:

the construction of fields of formal infinite series in several variables, generalizing the classical notion of formal Laurent series in one variable. Our discussion addresses the field operations for these series (addition, multiplication, and division), the composition, and includes an implicit function theorem.

Answer:
5xy^2z
Step-by-step explanation:
(-15/-3) x (x^6/x^5) x (y^5/y^3) x z = 5xy^2z
