Here we will show you how to calculate the cube root of 9 minus the cube root of 31. In other words, we will calculate ∛9 - ∛31.
To calculate the cube root of 9 minus the cube root of 31, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛9 ≈ 2.0801
∛31 ≈ 3.1414
2.0801 - 3.1414 = -1.0613
∛9 - ∛31 ≈ -1.0613
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 31 in its simplest radical form:
