What cube root equals 645? In other words, what number would you take the cube root of to get 645? To solve this problem, we want to find x in the following equation:
∛x = 645
To solve the ∛x = 645 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 645³
x = 645³
Then, we calculate 645³ to get the following answer:
645³ = 645 × 645 × 645
645³ = 268,336,125
∛268,336,125 = 645
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.
