What cube root equals 420? In other words, what number would you take the cube root of to get 420? To solve this problem, we want to find x in the following equation:
∛x = 420
To solve the ∛x = 420 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 420³
x = 420³
Then, we calculate 420³ to get the following answer:
420³ = 420 × 420 × 420
420³ = 74,088,000
∛74,088,000 = 420
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.
