What cube root equals 813? In other words, what number would you take the cube root of to get 813? To solve this problem, we want to find x in the following equation:
∛x = 813
To solve the ∛x = 813 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 813³
x = 813³
Then, we calculate 813³ to get the following answer:
813³ = 813 × 813 × 813
813³ = 537,367,797
∛537,367,797 = 813
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.
