What cube root equals 399? In other words, what number would you take the cube root of to get 399? To solve this problem, we want to find x in the following equation:
∛x = 399
To solve the ∛x = 399 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 399³
x = 399³
Then, we calculate 399³ to get the following answer:
399³ = 399 × 399 × 399
399³ = 63,521,199
∛63,521,199 = 399
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.
