In the variables x, y, z, a monomial is an expression of the form axmynzk, in which m, n, and k are nonnegative integers and a is a constant (e g , 5x2, 3x2y or 7x3yz2)
An algebraic expression consisting of a single term The single term can be a constant, a variable, or a product of a constant and one or more variables Each of the following is a monomial: 5 (a constant); x (a variable); -3z (a product of a constant and a variable); 6xyz ( a product of a constant and more than one variable)
