What cube root equals 721? In other words, what number would you take the cube root of to get 721? To solve this problem, we want to find x in the following equation:
∛x = 721
To solve the ∛x = 721 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 721³
x = 721³
Then, we calculate 721³ to get the following answer:
721³ = 721 × 721 × 721
721³ = 374,805,361
∛374,805,361 = 721
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.
