Here we will explain how to simplify the cube root of 2720 (∛2720). We start by labeling the parts of ∛2720 so it is easy to follow along:
∛2720 = 1∛2720 = c∛r
c = coefficient of the radical
∛ = radical
r = radicand
The cube root of 2720 in its simplest form means that you want the radicand to be as small as possible and the coefficient of the radical to be as large as possible.
To simplify the cube root of 2720, we first find the greatest perfect cube from the list of factors of 2720. The factors of 2720 are 1, 2, 4, 5, 8, 10, 16, 17, 20, 32, 34, 40, 68, 80, 85, 136, 160, 170, 272, 340, 544, 680, 1360, and 2720.
Any number multiplied by itself three times will make a perfect cube. The greatest perfect cube from the list of factors above is 8 (2 times 2 times 2 equals 8).
To find the simplified radicand (r) in the cube root of 2720, we divide 2720 by 8, which gives us 340.
To find the simplified coefficient of the radical (c) in the cube root of 2720, we take the cube root of 8, which gives us 2.
That is how you simplify the cube root of 2720. Therefore, the cube root of 2720 in its simplest radical form is as follows:
∛2720 = 2∛340
