Here we will show you how to calculate the cube root of 8 minus the cube root of 32. In other words, we will calculate ∛8 - ∛32.
To calculate the cube root of 8 minus the cube root of 32, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛32 ≈ 3.1748
2 - 3.1748 = -1.1748
∛8 - ∛32 ≈ -1.1748
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 32 in its simplest radical form:
