Here we will show you how to calculate the cube root of 9 minus the cube root of 7. In other words, we will calculate ∛9 - ∛7.
To calculate the cube root of 9 minus the cube root of 7, 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
∛7 ≈ 1.9129
2.0801 - 1.9129 = 0.1672
∛9 - ∛7 ≈ 0.1672
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 7 in its simplest radical form:
