Here we will show you how to calculate the cube root of 9 minus the cube root of 40. In other words, we will calculate ∛9 - ∛40.
To calculate the cube root of 9 minus the cube root of 40, we will first take the cube root of each number and then find the difference. Here is the math and the answer:
∛9 ≈ 2.0801
∛40 ≈ 3.42
2.0801 - 3.42 = -1.3399
∛9 - ∛40 ≈ -1.3399
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 40 in its simplest radical form:
