Question

Solve y³ = −8.
A. y = −2
B. y = ±2
C. y = 4
D. y = −4

Answer 1

To solve the equation y³ = -8, you need to take the cube root of both sides. The solution is y = -2.

Step-by-step explanation:

Equations are mathematical statements that assert the equality of two expressions. They contain variables, constants, and mathematical operations, and the goal is often to find the values of the variables that make the equation true. Equations play a central role in mathematics and are used in various fields to model relationships, solve problems, and make predictions.

To solve the equation y³ = -8, we need to take the cube root of both sides. The cube root of -8 is -2, so the solution to the equation is y = -2.

Therefore, the correct answer is A. y = -2.
