What cube root equals 309? In other words, what number would you take the cube root of to get 309? To solve this problem, we want to find x in the following equation:
∛x = 309
To solve the ∛x = 309 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 309³
x = 309³
Then, we calculate 309³ to get the following answer:
309³ = 309 × 309 × 309
309³ = 29,503,629
∛29,503,629 = 309
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.
