Here we will show you how to calculate the cube root of 14 plus the cube root of 18. In other words, we will calculate ∛14 + ∛18.
It is tempting to simply add 14 and 18 together and then take the cube root of the sum. However, that will give you the wrong answer. Instead, you have to first take the cube root of each number and then add them together, like this:
∛14 ≈ 2.4101
∛18 ≈ 2.6207
2.4101 + 2.6207 = 5.0308
∛14 + ∛18 ≈ 5.0308
For your convenience, we have also included the answer to the cube root of 14 plus the cube root of 18 in its simplest radical form:
∛14 + ∛18
