Fourth Root of 8
In this section we provide you with important additional information about the topic of this post:
The term can be written as ⁴√8 or 8^1/4.
As the index 4 is even and 8 is greater than 0, 8 has two real 4th roots:
⁴√8, which is positive and called principal 4th root of 8, and -⁴√8 which is negative.
Together, they are denominated as
Although the principal fourth root of eight is only one of the two 4th roots, the term “4th root of 8” 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 4th Root located in the header menu.
There, we also discuss the properties for index n8 = 4 by means of examples: multiplication, division, exponentiation etc.
Next, we have a look at the inverse function.
