\sqrt[4]{20} = \pm2.1147425269This 4th Root Calculator and Information is Really Cool! Click To TweetIf you have been looking for the 4th root of twenty, then you are right here, too.

The term can be written as \sqrt[4]{20} \hspace{3 mm}or\hspace{3 mm} 20^{1/4}.

As the index 4 is even and 20 is greater than 0, 20 has two real 4th roots: \sqrt[4]{20}, which is positive and called principal 4th root of 20, and −\sqrt[4]{20}, which is negative.

Together, they are denominated as ±\sqrt[4]{20}.

Although the principal fourth root of twenty is only one of the two 4th roots, the term “4th root of 20” usually refers to the positive number.

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 n = 4 by means of examples: multiplication, division, exponentiation etc.

Next, we have a look at the inverse function.
