What cube root equals 45? In other words, what number would you take the cube root of to get 45? To solve this problem, we want to find x in the following equation:
∛x = 45
To solve the ∛x = 45 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 45³
x = 45³
Then, we calculate 45³ to get the following answer:
45³ = 45 × 45 × 45
45³ = 91,125
∛91,125 = 45
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.
