In this lesson on Square Roots and Radicals, you will learn how to estimate the square roots of non-perfect square numbers. By identifying the perfect squares just below and just above the non-perfect square, you can estimate the square root to be between two whole numbers. This method can be done mentally or with a calculator, but it's important to remember that the answer is an approximation and not an exact value.
Learn about square roots of numbers that are not perfect squares. This video will teach you how to approximate irrational square roots between two whole numbers in your head as well as approximating their value on a calculator.
