Interpreting your equation as 13 = √(x − 1):
1. Square both sides: 13^2 = x − 1 → 169 = x − 1.
2. Solve for x: x = 169 + 1 = 170.
3. Check domain: x − 1 ≥ 0 → 170 ≥ 1, OK. Check: √(170 − 1) = √169 = 13.
So x = 170.
If you meant a different parsing (for example 13 = (√) − 1 + x or something else), please clarify.
