In this section we provide you with important additional information about the topic of this post:
The term can be written as ²√20 or 20^1/2.
As the index 2 is even and 20 is greater than 0, 20 has two real square roots:
²√20, which is positive and called principal square root of 20, and -²√20 which is negative.
Together, they are denominated as
Although the principal square root of twenty is only one of the two square roots, the term “square root of 20” usually refers to the positive number, that is the principal square root.
If you want to know how to find the value of this root, then read our article Square Root located in the header menu.
There, we also discuss the properties for index n = 2 by means of examples: multiplication, division, exponentiation etc.
Next, we have a look at the inverse function.
