Here we will show you how to calculate the cube root of 9 minus the cube root of 16. In other words, we will calculate ∛9 - ∛16.
To calculate the cube root of 9 minus the cube root of 16, 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
∛16 ≈ 2.5198
2.0801 - 2.5198 = -0.4397
∛9 - ∛16 ≈ -0.4397
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 16 in its simplest radical form:
