Here we will show you how to calculate the cube root of 9 minus the cube root of 88. In other words, we will calculate ∛9 - ∛88.
To calculate the cube root of 9 minus the cube root of 88, 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
∛88 ≈ 4.448
2.0801 - 4.448 = -2.3679
∛9 - ∛88 ≈ -2.3679
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 88 in its simplest radical form:
