Here we will show you how to calculate the cube root of 8 minus the cube root of 30. In other words, we will calculate ∛8 - ∛30.
To calculate the cube root of 8 minus the cube root of 30, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛30 ≈ 3.1072
2 - 3.1072 = -1.1072
∛8 - ∛30 ≈ -1.1072
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 30 in its simplest radical form:
2 - ∛30
