Cube root of 8 Here we will show you the answer to the cube root of 8 in decimal form and in its simplest radical form. But before that, we start by showing you the cube root of 8 written in mathematical terms:

8

The √ is called the radical symbol, the little 3 is the index which means cube, and 8 is the radicand.

The cube root of 8 is a number (n) that when multiplied by itself twice will equal 8. In other words, the cube root of 8 is the number (n) in the following equation:

n × n × n = 8

8 is the same as 8. Therefore, to solve the problem in Excel or Numbers, you can enter 8^(1/3) to get the answer to the cube root of 8. However, we used a scientific calculator and typed in 8 and then pressed the [∛x] button. We got the following answer:

8 = 2

You can simplify the cube root of 8 if you can make the radicand smaller. This is called the cube root of 8 in its simplest radical form. The answer to the cube root 8 in its simplest form is displayed below:

8 = 2
