Hi, and welcome to this video on roots! Today, we will be working towards an understanding of the terminology, notation, and interpretation of algebraic roots. We will also be making connections to other concepts that you will need in higher-level math. Let’s get started!
Understanding the terminology and notation of math is half the battle if you’re struggling to grasp certain concepts. This is true of roots, where the terminology that is used determines the “type” of root that is evaluated.
To find the square root of a number, simply ask yourself, “what value, when multiplied[1] by itself, results in that number?”
For example, let’s say you were asked to find the square root of 4. Ask yourself, “what value, when multiplied by itself, results in 4?” The answer is 2, because 2 times 2 equals 4.
Let’s try another one. What is the square root of 121? Ask yourself, “what value, when multiplied by itself, results in 121?” The answer is 11, because 11 times 11 equ...
