What cube root equals 820? In other words, what number would you take the cube root of to get 820? To solve this problem, we want to find x in the following equation:
∛x = 820
To solve the ∛x = 820 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 820³
x = 820³
Then, we calculate 820³ to get the following answer:
820³ = 820 × 820 × 820
820³ = 551,368,000
∛551,368,000 = 820
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.
