What Is a Root?

A root is a mathematical operation that determines the value which, when multiplied by itself a specified number of times, equals the given number. The most common root is the square root, denoted by \( \sqrt{a} \), which represents the second root of a number. In general, the \( n \)-th root is expressed as \( \sqrt[n]{a} \), which finds a number \( x \) such that: \( x^n = a \).

Examples

Example 1: Calculate the square root of 16.

Solution:

Compute:

\( x = \sqrt{16} = 4 \)

Conclusion: The square root of 16 is 4.

Example 2: Calculate the cube root of 27.

Solution:

Compute:

\( x = \sqrt[3]{27} = 3 \)

Conclusion: The cube root of 27 is 3.

Example 3: Calculate the fourth root of 81.

Solution:

Compute:

\( x = \sqrt[4]{81} = 3 \)

Conclusion: The fourth root of 81 is 3.

Example 4: Calculate the cube root of 1000.

Solution:

Compute:

\( x = \sqrt[3]{1000} = 10 \)

Conclusion: The cube root of 1000 is 10.
