Here we will show you how to calculate the cube root of 9 minus the cube root of 99. In other words, we will calculate ∛9 - ∛99.
To calculate the cube root of 9 minus the cube root of 99, 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
∛99 ≈ 4.6261
2.0801 - 4.6261 = -2.546
∛9 - ∛99 ≈ -2.546
For your convenience, we have also included the answer to the cube root of 9 minus the cube root of 99 in its simplest radical form:
