Simplify Cube Root of 168

Here we will show you step-by-step how to simplify the cube root of 168. Before we continue, note that the cube root of 168 can be written as follows:

∛168

The ∛ symbol is called the radical sign. To simplify the cube root of 168 means to get the simplest radical form of ∛168.

Step 1: List Factors
We start by listing the factors of 168 like so:

1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, and 168

Step 2: Find Perfect Cubes
Next, we identify the perfect cubes* from the list of factors above:

1 and 8

Step 3: Find the number to go inside the radical
From the list of perfect cubes, you see that 8 is the largest perfect cube. Now, divide 168 by the largest perfect cube to find the number that will go inside the radical.

168 / 8 = 21

Step 4: Find the number to go outside the radical
To find the number that will go outside the radical, we simply calculate the cube root of the largest perfect cube:

∛8 = 2

Step 5: Get the answer
Put Steps 3 and 4 together to get the cube root of 168 in its simplest radical form. You put the result from Step 3 inside the radical and the result from Step 4 outside the radical:

2∛21
