To find the value of y in the equation y³ = 27, we can use the method of taking the cube root of both sides of the equation. The cube root is the opposite operation of cubing a number.
Here’s how the calculation works:
- Start with the equation:
- y³ = 27
- Now, to solve for y, take the cube root of both sides:
- y = ∛27
- Since 3 x 3 x 3 equals 27, we find that y = 3.
So, the calculation we used is the cube root, and the final value of y is 3.
