X3-76=56

To solve the equation \( x^3 - 76 = 56 \), follow these steps:

1. Add 76 to both sides of the equation to isolate \( x^3 \): \[ x^3 = 56 + 76 \] \[ x^3 = 132 \]

2. Now, take the cube root of both sides to solve for \( x \): \[ x = \sqrt[3]{132} \]

3. You can calculate \( \sqrt[3]{132} \): \[ x \approx 5.072 \]

So, the approximate solution is \( x \approx 5.072 \). If you need a more precise value, use a calculator to find the cube root.
