What are Monomials?

Monomials are a fundamental concept in algebra and are used to represent variables and their powers. A monomial is a polynomial expression that consists of a single term, which is a product of variables and/or constants.

For example, the following are monomials:

* 3x^2
* 2y
* z^4
* 5x
* 2ab

In each case, the expression is a product of one or more variables and/or constants, with no additional operations (such as addition or subtraction) performed on them.

Monomials are important in algebra because they can be added and multiplied to form more complex expressions, such as polynomials and equations. Understanding monomials is essential for solving algebraic problems and understanding more advanced concepts, such as polynomial long division and the factoring of polynomials.
