Here we will show you how to calculate the cube root of 9 minus the cube root of 63. In other words, we will calculate ∛9 - ∛63.
To calculate the cube root of 9 minus the cube root of 63, 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
∛63 ≈ 3.9791
2.0801 - 3.9791 = -1.899
∛9 - ∛63 ≈ -1.899
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 63 in its simplest radical form:
