Unit 4: Exponents and Radicals

Have you ever wanted to explore how things in the universe either grow or shrink in size? The use of exponents fills the mathematical need to efficiently represent very large numbers and very small numbers. Exponent rules can be applied to integers, radicals, and fractions to make math operations faster and solutions easier to interpret. Scientists use exponents and their rules to represent the large distances between planets or stars, or very small masses such as that of an atom.

Lesson 4.1: Prime Factors, Greatest Common Factors, and Least Common Multiples

Lesson 4.1 Video link here.
Suppose you want to create secure access to a computer system within a company. How could this be done so only employees have access to the system? Is it possible to encrypt the system to increase security?

Computer programmers use algorithms involving large prime numbers and factors to secure most systems.

In this lesson, you will learn about prime factors, greatest common factors (GCF), and least common multiples (LCM).
