Here we will show you how to calculate the cube root of 9 minus the cube root of 3. In other words, we will calculate ∛9 - ∛3.
To calculate the cube root of 9 minus the cube root of 3, 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
∛3 ≈ 1.4422
2.0801 - 1.4422 = 0.6379
∛9 - ∛3 ≈ 0.6379
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 3 in its simplest radical form:
∛9 - ∛3
