Here we will show you how to calculate the cube root of 22 minus the cube root of 20. In other words, we will calculate ∛22 - ∛20.
To calculate the cube root of 22 minus the cube root of 20, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛22 ≈ 2.802
∛20 ≈ 2.7144
2.802 - 2.7144 = 0.0876
∛22 - ∛20 ≈ 0.0876
For your convenience, we have also included the answer to the cube root of 22 minus the cube root of 20 in its simplest radical form:
