Here we will show you step-by-step how to simplify the cube root of 9. Before we continue, note that the cube root of 9 can be written as follows:
∛9
The ∛ symbol is called the radical sign. To simplify the cube root of 9 means to get the simplest radical form of ∛9.
We start by listing the factors of 9 like so:
1, 3, and 9
Next, we identify the perfect cubes* from the list of factors above:
1
Since 1 is the only perfect cube above, the cube root of 9 cannot be simplified.
Although we cannot simplify the cube root of 9, we did enter the cube root of 9 into our calculator and got the following answer to the cube root of 9 in decimal form:
∛9 ≈ 2.0801
