Questions: Find the real solutions of the following equation.
(4 x-4)^(1/3)=-4
Transcript text: Find the real solutions of the following equation.
\[
(4 x-4)^{\frac{1}{3}}=-4
\]
Solution
Solution Steps
To find the real solutions of the given equation \((4x - 4)^{\frac{1}{3}} = -4\), we need to isolate \(x\). We can start by cubing both sides of the equation to eliminate the cube root, and then solve for \(x\).
Step 1: Cube Both Sides of the Equation
To eliminate the cube root, we cube both sides of the equation:
\[
\left( (4x - 4)^{\frac{1}{3}} \right)^3 = (-4)^3
\]
This simplifies to:
\[
4x - 4 = -64
\]
Step 2: Solve for \(x\)
Next, we solve for \(x\) by isolating it on one side of the equation:
\[
4x - 4 = -64
\]
Add 4 to both sides:
\[
4x = -60
\]
Divide both sides by 4:
\[
x = -15
\]
