Rainboy always hated irrational numbers and he hated radicals even more, to irritate him RadeWoosh came up with a very irritating problem which involved irrational numbers. The problem can be formally stated as below:

RadeWoosh wants Rainboy to express $(\sqrt{3}-\sqrt{2})^{999.....9 (18 digits)}$ as $\sqrt{a} -\sqrt{b}$ where a and b are consecutive whole numbers and $a > b$. Help Rainboy to find the $a$ modulo $1000000007$.
