What cube root equals 638? In other words, what number would you take the cube root of to get 638? To solve this problem, we want to find x in the following equation:
∛x = 638
To solve the ∛x = 638 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 638³
x = 638³
Then, we calculate 638³ to get the following answer:
638³ = 638 × 638 × 638
638³ = 259,694,072
∛259,694,072 = 638
We made the equation above so you will get a full understanding of how to solve problems like this. In the future, note that you can solve all similar problems by simply multiplying the number by itself twice to get the answer.
