What cube root equals 256? In other words, what number would you take the cube root of to get 256? To solve this problem, we want to find x in the following equation:
∛x = 256
To solve the ∛x = 256 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 256³
x = 256³
Then, we calculate 256³ to get the following answer:
256³ = 256 × 256 × 256
256³ = 16,777,216
∛16,777,216 = 256
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.
