What cube root equals 644? In other words, what number would you take the cube root of to get 644? To solve this problem, we want to find x in the following equation:
∛x = 644
To solve the ∛x = 644 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 644³
x = 644³
Then, we calculate 644³ to get the following answer:
644³ = 644 × 644 × 644
644³ = 267,089,984
∛267,089,984 = 644
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.
