Here we will explain how to simplify the cube root of 656 (∛656). We start by labeling the parts of ∛656 so it is easy to follow along:
∛656 = 1∛656 = c∛r
c = coefficient of the radical
∛ = radical
r = radicand
The cube root of 656 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 656, we first find the greatest perfect cube from the list of factors of 656. The factors of 656 are 1, 2, 4, 8, 16, 41, 82, 164, 328, and 656.
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 656, we divide 656 by 8, which gives us 82.
To find the simplified coefficient of the radical (c) in the cube root of 656, we take the cube root of 8, which gives us 2.
That is how you simplify the cube root of 656. Therefore, the cube root of 656 in its simplest radical form is as follows:
∛656 = 2∛82
