If by "xn" you mean ax^n then the answer is "a"
It's a monomial of 1st degree (linear). "3x over seven" = (3/7)x The x term (indeed the ONLY term -- hence monomial) has a coefficient of 3/7. Since the variable x appears to the 1st power, it's 1st degree.
Yes, it is.
false
Yes, it is.
The degree of a term is the sum of the exponents on the variables.
A monomial with a coefficient if often called a term.
4x2y The degree of the monomial is 2.
A monomial is a special case of a polynomial which contains only one term. To identify a particular term of a polynomial (in x), we use the name associated with the power of x contained in a term. 3 + √7 is a monomial of zero degree which has a special name such as a constant polynomial. Let's rewrite it as, 3x0 + (√2)x0 = (3 + √7)x0 , a monomial with an irrational coefficient = (3 + √7)(1) = 3 + √7.
You start with the monomial of highest degree followed by the next monomial and continue till you have listed them all with the one of highest degree first and the lowest degree last. The last term is often a number (constant). ( in case you forgot, a monomial is a polynomial with only one term.) The simplest form part just means combine any like terms. I would suggest doing that first.
true
A number before a variable (letter) is called the coefficient of the variable. Both of them makes a term, or a monomial.
Every term of a polynomial is a monomial.
