In this section we provide you with important additional information about the topic of this post:
The term can be written as ²√40 or 40^1/2.
As the index 2 is even and 40 is greater than 0, 40 has two real square roots:
²√40, which is positive and called principal square root of 40, and -²√40 which is negative.
Together, they are denominated as
Although the principal square root of forty is only one of the two square roots, the term “square root of 40” usually refers to the positive number, that is the principal square root.
