Here we will show you how to calculate the cube root of 9 minus the cube root of 85. In other words, we will calculate ∛9 - ∛85.
To calculate the cube root of 9 minus the cube root of 85, 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
∛85 ≈ 4.3968
2.0801 - 4.3968 = -2.3167
∛9 - ∛85 ≈ -2.3167
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 85 in its simplest radical form:
