Here we will show you how to calculate the cube root of 8 minus the cube root of 13. In other words, we will calculate ∛8 - ∛13.
To calculate the cube root of 8 minus the cube root of 13, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛13 ≈ 2.3513
2 - 2.3513 = -0.3513
∛8 - ∛13 ≈ -0.3513
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 13 in its simplest radical form:
2 - ∛13
