Here we will explain how to simplify the cube root of 90 (∛90). We start by labeling the parts of ∛90 so it is easy to follow along:
∛90 = 1∛90 = c∛r
c = coefficient of the radical
∛ = radical
r = radicand
The cube root of 90 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 90, we first find the greatest perfect cube from the list of factors of 90. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
Any number multiplied by itself three times will make a perfect cube. The greatest perfect cube from the list of factors above is 1 (1 times 1 times 1 equals 1).
To find the simplified radicand (r) in the cube root of 90, we divide 90 by 1, which gives us 90.
To find the simplified coefficient of the radical (c) in the cube root of 90, we take the cube root of 1, which gives us 1.
That is how you simplify the cube root of 90. Therefore, the cube root of 90 in its simplest radical form is as follows:
∛90 = ∛90
