Solving the Equation: (-8-2x)^(1/3) = (-3-x)^(1/3)
This equation involves cube roots, which can be a bit tricky to deal with. However, we can simplify it by using the following properties:
- If a^(1/3) = b^(1/3), then a = b. This means we can get rid of the cube roots by cubing both sides of the equation.
Let's break down the solution step-by-step:
-
Cube both sides:
[(-8-2x)^(1/3)]^3 = [(-3-x)^(1/3)]^3
-
Simplify:
-8 - 2x = -3 - x
-
Solve for x:
-2x + x = -3 + 8 -x = 5 x = -5
Therefore, the solution to the equation (-8-2x)^(1/3) = (-3-x)^(1/3) is x = -5.
Important Note: Always check your solutions by plugging them back into the original equation to ensure they are valid. In this case, plugging x = -5 into the original equation does indeed work, confirming that our solution is correct.
