In math, the **5th root** *b* of a number *a* is such that b^{5} = a. By definition, when you multiply b by itself *5* times you get the value of a.

A 5-th root is usually denoted ^{5}√x, but it can also be written in exponential form with the base *x* and the exponent 1/5: x^1/5 or x^{1/5}.

Read on to learn everything about these numbers, including the properties, and make sure to check out our calculator.

If you happen to know exponentiation, then you can think of the 5th root of a number as the inverse operation to elevating a number to the power of 5.

## Definition

Whereas in exponentiation elevating a number *a* to the power of 5 is defined as a^{5} = b, the 5th root *b* is defined as b = a^{1/5}.

For example with a = 7776 we get:

In other words, the 5th root of 7776 is 6, because 6 times 6 times 6 times 6 times 6 is 7776.

As the index n (5) is odd, 5 is the only real 5th root.

Next, we explain how the parts are called. Keep reading to learn all about the topic.

## Parts

As depicted, the parts of the fifth root are:

The radix sign, which tells us that it is a mathematical root, and the index of *5*, which tells us that it is the 5-th root.

The number below the radix, x, is the radicand.

The result of the mathematical operation is denoted by the equal sign and called the root.

### 5th Root Symbol

The symbol √ is called radical sign, or radix.

## How to Calculate the 5th Root

A very efficient procedure for extracting the fifth root is the Newton–Raphson method, also known as Newton’s method detailed below:

You begin with a guessed starting value and then iterate the steps until you’re happy with the precision.

In the most basic version of the method, f is a single-variable function and f′ its derivative.

You may think of it as the 5th root formula.
