Solution 1

Denote $x = \log_b n$. Hence, the system of equations given in the problem can be rewritten as \begin{align*} \sqrt{x} & = \frac{1}{2} x . \\ bx & = 1 + x . \end{align*}

Thus, $x = 4$ and $b = \frac{5}{4}$. Therefore, \begin{align*} n & = b^x \\ & = \frac{625}{256} . \end{align*}

Therefore, the answer is $625 + 256 = \boxed{\textbf{(881) }}$.
