Here we will show you how to calculate the cube root of 8 minus the cube root of 40. In other words, we will calculate ∛8 - ∛40.
To calculate the cube root of 8 minus the cube root of 40, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛40 ≈ 3.42
2 - 3.42 = -1.42
∛8 - ∛40 ≈ -1.42
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 40 in its simplest radical form:
