What cube root equals 405? In other words, what number would you take the cube root of to get 405? To solve this problem, we want to find x in the following equation:
∛x = 405
To solve the ∛x = 405 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 405³
x = 405³
Then, we calculate 405³ to get the following answer:
405³ = 405 × 405 × 405
405³ = 66,430,125
∛66,430,125 = 405
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.
