Let's solve the quadratic equations one by one.

1. **Equation:** \((x + 6)^2 = 8\)
- Take the square root of both sides:
\[
x + 6 = \pm \sqrt{8}
\]
\(\sqrt{8} = 2\sqrt{2}\), so we get:
\[
x + 6 = 2\sqrt{2} \quad \text{or} \quad x + 6 = -2\sqrt{2}
\]
- Solving these gives:
\[
x = 2\sqrt{2} - 6 \quad \text{or} \quad x = -2\sqrt{2} - 6
\]

2. **Equation:** \(x^2 = 36169\)
- Taking the square root of both sides:
\[
x = \pm \sqrt{36169}
\]
Since \(36169 = 189^2\):
\[
x = 189 \quad \text{or} \quad x = -189
\]
- The solution set is \(\{-189, 189\}\).

3. **Next Equation:** \(8^2 = 196\)
- This appears to be checking for \(8^2\) equaling \(196\), but \(8^2 = 64\). Therefore, the equation is incorrect. Let’s assume that the original intention was \(x^2 = 196\).
- Taking the square root of both sides:
\[
x = \pm \sqrt{196}
\]
Since \(196 = 14^2\):
\[
x = 14 \quad \text{or} \quad x = -14
\]
- The solution set is \(\{14, -14\}\).

### Final Responses:

1. For \((x + 6)^2 = 8\):
- Solutions: \(x = 2\sqrt{2} - 6\) and \(x = -2\sqrt{2} - 6\) (exact roots)

2. For \(x^2 = 36169\):
- Solution set: \(\{-189, 189\}\)

3. For \(x^2 = 196\) (if it was intended):
- Solution set: \(\{14, -14\}\).
