What cube root equals 689? In other words, what number would you take the cube root of to get 689? To solve this problem, we want to find x in the following equation:
∛x = 689
To solve the ∛x = 689 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 689³
x = 689³
Then, we calculate 689³ to get the following answer:
689³ = 689 × 689 × 689
689³ = 327,082,769
∛327,082,769 = 689
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.
