Simplify Cube Root of 8720

Here we will show you step-by-step how to simplify the cube root of 8720. Before we continue, note that the cube root of 8720 can be written as follows:

∛8720

The ∛ symbol is called the radical sign. To simplify the cube root of 8720 means to get the simplest radical form of ∛8720.

Step 1: List Factors
We start by listing the factors of 8720 like so:

1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 109, 218, 436, 545, 872, 1090, 1744, 2180, 4360, and 8720

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 8720 by the largest perfect cube to find the number that will go inside the radical.

8720 / 8 = 1090

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 8720 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∛1090
