**Solve the Equation**

\[ \sqrt{(X + 30)} = X + 10 \] 

To solve this equation:

1. **Isolate the square root**: It's already isolated on the left side of the equation.

2. **Square both sides** to eliminate the square root:
   \[ X + 30 = (X + 10)^2 \]

3. **Expand the right side**:
   \[ X + 30 = X^2 + 20X + 100 \]

4. **Rearrange the equation to set it to zero**:
   \[ X^2 + 20X + 100 - X - 30 = 0 \]
   \[ X^2 + 19X + 70 = 0 \]

5. **Solve the quadratic equation** using the quadratic formula or factoring, if possible.

6. **Check the solutions** to ensure they satisfy the original equation, as squaring can introduce extraneous solutions.
