Here we will show you how to calculate the cube root of 8 minus the cube root of 4. In other words, we will calculate ∛8 - ∛4.
To calculate the cube root of 8 minus the cube root of 4, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛4 ≈ 1.5874
2 - 1.5874 = 0.4126
∛8 - ∛4 ≈ 0.4126
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 4 in its simplest radical form:
2 - ∛4
