If 13%286%5E2%2F%285%5E2-4%5E2%29%2B9%29 is the expression you meant to represent, then your answer, 169, is correct.

On the other hand, if you really meant 13%286%5E2%2F%28%285%5E2-4%5E2%29%2B9%29%29, then the answer is significantly different.

13%286%5E2%2F%28%285%5E2-4%5E2%29%2B9%29%29=13%2836%2F%2825-16%2B9%29%29=13%2836%2F18%29=13%2A2=26
