Here we will explain how to simplify the cube root of 7889 (∛7889). We start by labeling the parts of ∛7889 so it is easy to follow along:
∛7889 = 1∛7889 = c∛r
c = coefficient of the radical
∛ = radical
r = radicand
The cube root of 7889 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 7889, we first find the greatest perfect cube from the list of factors of 7889. The factors of 7889 are 1, 7, 23, 49, 161, 343, 1127, and 7889.
Any number multiplied by itself three times will make a perfect cube. The greatest perfect cube from the list of factors above is 343 (7 times 7 times 7 equals 343).
To find the simplified radicand (r) in the cube root of 7889, we divide 7889 by 343, which gives us 23.
To find the simplified coefficient of the radical (c) in the cube root of 7889, we take the cube root of 343, which gives us 7.
That is how you simplify the cube root of 7889. Therefore, the cube root of 7889 in its simplest radical form is as follows:
∛7889 = 7∛23
