Question

Solve the equation y³ = -27.
1) y = ±3
2) y = -3
3) y = -9
4) y = ±9

Answer 1

To solve the equation y³ = -27, find the cube root of -27, which is -3. Therefore, y = -3.

Step-by-step explanation:

To solve the equation y³ = -27, we need to find the cube root of -27. The cube root of a number is a number that, when raised to the power of 3, gives the original number.

The cube root of -27 is -3, because (-3)³ = -27.

Therefore, the solution to the equation is y = -3 (option 2).
