  1. Algebra I - Chapter 4 4.1 Exponents

  2. Exponents N 4 = Remember that the power just deals with the variable in front of it. MN2 (MN)2

  3. Let’s Try Some: • Evaluate if a = 3 and b = -2 ab – a2 a3 + 2b3

  4. Vocabulary: • A monomial is an expression that is a number, a variable, or the product of a number and one or more variables They cannot contain variables in denominators, variables with exponents that are negative, or variables under radicals • Constants are monomials that contain no variables • The numerical factor of a monomial is the coefficient of the variable

  5. More Vocabulary: A Polynomial is a monomial or a sum of monomials The monomials that make up a polynomial are called the terms of the polynomial Like terms are the ones that can be combined

  6. Vocabulary: • The degree of a monomial is the sum of the exponents of it variables – the degree of a constant is zero

  7. Even More Vocab! • Binomials (two terms) • Trinomial (three terms) • The degree is the degree of the monomial with the greatest degree
