Here we will show you how to calculate the cube root of 9 minus the cube root of 79. In other words, we will calculate ∛9 - ∛79.
To calculate the cube root of 9 minus the cube root of 79, 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
∛79 ≈ 4.2908
2.0801 - 4.2908 = -2.2107
∛9 - ∛79 ≈ -2.2107
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 79 in its simplest radical form:
