What cube root equals 642? In other words, what number would you take the cube root of to get 642? To solve this problem, we want to find x in the following equation:
∛x = 642
To solve the ∛x = 642 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 642³
x = 642³
Then, we calculate 642³ to get the following answer:
642³ = 642 × 642 × 642
642³ = 264,609,288
∛264,609,288 = 642
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.
