About This Chapter
Understanding Square Roots - Chapter Summary
Our subject-matter experts have developed this set of lessons for those who need help with understanding square roots. Discover how to evaluate the perfect square and how to work with other scenarios like:
- Finding a number's square root
- Estimation of a square root
- Simplifying a square root simple when it's not a perfect square
- Expression simplification when that expression contains a square root
Our instructors host these illustrated and easy-to-follow video lessons, with each lesson having its own self-assessment quiz that you can use to check your understanding of what you just studied. You can submit any question you have directly to the instructor.
1. How to Find the Square Root of a Number
What is a square root? In this lesson, we'll learn what a square root is and how to find it. We'll review a variety of examples in order to master the concept.
2. Evaluating Square Roots of Perfect Squares
Squares and square roots are inverse, or opposite, operations involving radicals. Learn how to determine the square root of perfect squares in this lesson.
3. Estimating Square Roots
Inverse operations are mathematical operations that undo each other. The square root is the inverse of the squared (or multiplying a number by itself) operation. There is an easy method for estimating the square root of a number, which you will learn in this lesson.
4. Simplifying Square Roots When not a Perfect Square
Numbers that are imperfect squares are those that, when evaluated, do not give solutions that are integers. The proper mathematical way to simplify these imperfect squares is discussed in this lesson.
5. Simplifying Expressions Containing Square Roots
In order to write radical expressions correctly, they have to be written in their simplest form. This lesson will show you how to simplify expressions containing numbers and variables inside a square root.
