The answer is 26.
The method for solving depends on the resources available and your mathematical ability.
With a computer or calculator, the solution is trivial.
You could try trial and improvement or, a more sophisticated way is the Newton Raphson method which will work for all kinds of roots.
Finally, there is a method that resembles long division that can be applied to square roots but I regret that I am not up to describing it through this browser.
