What cube root equals 289? In other words, what number would you take the cube root of to get 289? To solve this problem, we want to find x in the following equation:
∛x = 289
To solve the ∛x = 289 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 289³
x = 289³
Then, we calculate 289³ to get the following answer:
289³ = 289 × 289 × 289
289³ = 24,137,569
∛24,137,569 = 289
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.
