What cube root equals 648? In other words, what number would you take the cube root of to get 648? To solve this problem, we want to find x in the following equation:
∛x = 648
To solve the ∛x = 648 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 648³
x = 648³
Then, we calculate 648³ to get the following answer:
648³ = 648 × 648 × 648
648³ = 272,097,792
∛272,097,792 = 648
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.
