What cube root equals 138? In other words, what number would you take the cube root of to get 138? To solve this problem, we want to find x in the following equation:
∛x = 138
To solve the ∛x = 138 equation, we first raise both sides to the power of 3 to eliminate the cube root:
(∛x)³ = 138³
x = 138³
Then, we calculate 138³ to get the following answer:
138³ = 138 × 138 × 138
138³ = 2,628,072
∛2,628,072 = 138
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.
