Here we will show you how to calculate the cube root of 8 minus the cube root of 66. In other words, we will calculate ∛8 - ∛66.
To calculate the cube root of 8 minus the cube root of 66, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛8 = 2
∛66 ≈ 4.0412
2 - 4.0412 = -2.0412
∛8 - ∛66 ≈ -2.0412
For your convenience, we have also included the answer to the cube root of 8 minus the cube root of 66 in its simplest radical form:
