The degree of a term is the sum of the exponents on the variables.
4x2y The degree of the monomial is 2.
It is Eighteen
The monomial -2 has a degree of 0.
Every term of a polynomial is a monomial.
If by "xn" you mean ax^n then the answer is "a"
yea
The degree of a monomial is determined by the exponent of its variable. In the case of the monomial (-7x^4), the exponent of (x) is 4. Therefore, the degree of the monomial (-7x^4) is 4.
The "degree" is only specified for polynomials. The degree of a monomial (a single term) is the sum of the powers of all the variables. For example, x3y2z would have the degree 6; you have to add 3 + 2 + 1 (since z is the same as z to the power 1). The degree of a polynomial is the degree of its highest monomial.
