# Binomial Coeffieients

$\large \displaystyle\sum_{i=0}^{264}(-1)^{i}\binom {529}{2i}$

If the value of the summation above is in the form $$a^b$$, where $$a$$ and $$b$$ are positive integers with $$a$$ is minimized, enter $$a+b$$.

Notation: $$\binom MN$$ denotes the binomial coefficient, $$\binom MN = \frac{M!}{N!(M-N)!}$$.
