This is a review of basic powers and roots. In this class you should already know this as it is a prerequisite, but it never hurts to review.
- 14.2.1.1: Algebraic Expressions and Formulas
- In algebra, letters called variables are used to represent numbers. Combinations of variables and numbers along with mathematical operations form algebraic expressions, or just expressions.
- 14.2.1.2: Rules of Exponents and Scientific Notation
- In this section, we review the rules of exponents. Recall that if a factor is repeated multiple times, then the product can be written in exponential form xⁿ. The positive integer exponent n indicates the number of times the base x is repeated as a factor.
- 14.2.1.3: Roots and Radicals
- Review of powers and roots.
- 14.2.1.4: The Binomial Theorem
- A binomial is a polynomial with exactly two terms. The binomial theorem gives a formula for expanding (x+y)ⁿ for any positive integer n.
