What cube root equals 647? In other words, what number would you take the cube root of to get 647? To solve this problem, we want to find x in the following equation:
∛x = 647
To solve the ∛x = 647 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 647³
x = 647³
Then, we calculate 647³ to get the following answer:
647³ = 647 × 647 × 647
647³ = 270,840,023
∛270,840,023 = 647
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.
