Here we will show you how to calculate the cube root of 9 minus the cube root of 69. In other words, we will calculate ∛9 - ∛69.
To calculate the cube root of 9 minus the cube root of 69, 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
∛69 ≈ 4.1016
2.0801 - 4.1016 = -2.0215
∛9 - ∛69 ≈ -2.0215
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 69 in its simplest radical form:
