WebCube Root of 216 Solved Examples Example 1: Find the real root of the equation x3 − 216 = 0. Solution: x 3 − 216 = 0 i.e. x 3 = 216 Solving for x gives us, x = ∛216, x = ∛216 × (-1 + √3i))/2 and x = ∛216 × (-1 - √3i))/2 where i is called the imaginary unit and is equal to √-1. Ignoring imaginary roots, x = ∛216 WebA cube root is an exponent of one-third. Square roots of negative numbers do not have real number roots since the product of any real number and itself is positive. Cube roots do exist for negative numbers since the product of three negatives is a negative. Students also learn to simplify a cube root by setting up a factor tree for the number ...

Have a … WebOct 6, 2024 · A cube root is simplified if it does not contain any factors that can be written as perfect cubes. The idea is to identify the largest cube factor of the radicand and then apply the product or quotient rule for radicals. As an example, to simplify \sqrt [ 3 ] { 80 }, notice that 80 is not a perfect cube. However, 80 = 8 ⋅ 10 and we can write, software brave
