What cube root equals 840? In other words, what number would you take the cube root of to get 840? To solve this problem, we want to find x in the following equation:
∛x = 840
To solve the ∛x = 840 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 840³
x = 840³
Then, we calculate 840³ to get the following answer:
840³ = 840 × 840 × 840
840³ = 592,704,000
∛592,704,000 = 840
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.
