Here we will explain how to simplify the cube root of 7928 (∛7928). We start by labeling the parts of ∛7928 so it is easy to follow along:
∛7928 = 1∛7928 = c∛r
c = coefficient of the radical
∛ = radical
r = radicand
The cube root of 7928 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 7928, we first find the greatest perfect cube from the list of factors of 7928. The factors of 7928 are 1, 2, 4, 8, 991, 1982, 3964, and 7928.
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 7928, we divide 7928 by 8, which gives us 991.
To find the simplified coefficient of the radical (c) in the cube root of 7928, we take the cube root of 8, which gives us 2.
That is how you simplify the cube root of 7928. Therefore, the cube root of 7928 in its simplest radical form is as follows:
∛7928 = 2∛991
