Here we will show you how to calculate the cube root of 9 minus the cube root of 15. In other words, we will calculate ∛9 - ∛15.
To calculate the cube root of 9 minus the cube root of 15, 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
∛15 ≈ 2.4662
2.0801 - 2.4662 = -0.3861
∛9 - ∛15 ≈ -0.3861
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 15 in its simplest radical form:
