XY is not a monomial, and explain why
A single number or letter is also called a monomial, so is 1 a monomial?

Yes,
A single number or letter is also called a monomial. For example, Mn is the product of numbers, letters M and N, which is a monomial

Write a monomial with the letter XY
Write a letter: XY 5 times
monomial

3xy
6xy

Is one of XY monomials? Why?

No, monomials are a kind of integers and polynomials. Algebraic expressions are divided into integers and fractions
Integers are divided into monomials and polynomials

(1) The expression of () is called a monomial. In particular, a single number or letter is also a monomial
(2) (3) in a binomial, the exponent of all letters is called the times of the binomial. The times of a single number can be regarded as the times of the binomial
(1) The () of several monomials are called polynomials. Each of them is called () of polynomials. The term without letters is called ()
(2) The degree of the term of degree () in a polynomial is called the degree of a polynomial. A polynomial with several terms is called several polynomials

(1) In particular, a single number or letter is also a monomial. (2) the (number factor) in a monomial is called the coefficient of the monomial. (3) in a monomial, the (sum) of the exponents of all letters is called the number of times of the monomial

If we know the binomial of - XY ^ 2A + 1 with respect to X and y, we can find (a + 1) ^ 2 + (A-1) ^ 2

-XY ^ 2A + 1 on X, Y's binomial 2A + 1 = 5, a = 2
(a+1)^2+(a-1)^2=3^2+1^2=10
