EASY TO HAI

$) {xy \frac{ \sqrt[ \sqrt{ \frac{ \frac{ { { { { \frac{ \frac{ \sqrt[ \sqrt[ \sqrt[ | | | | | | \leqslant \geqslant \geqslant \geqslant \geqslant \leqslant ))x { \frac{ \frac{ \frac{ \sqrt{ \sqrt{ \frac{ {xyy5122522..21. = .052............2355 + 152224 \beta \gamma log( \alpha \beta \gamma \gamma \binom{ \binom{ \alpha \pi \beta \piks \gamma \pi\pi\pi \csc( \csc( \gamma \tan(\pi\%) ) ) }{?} }{?} ) }^{2} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} }{?} } } }{?} }{?} }{?} \times \frac{?}{?} }^{2} | | | | | | ]{?} \times \frac{?}{?} ]{?} ]{?} }{?} }{?} }^{2} }^{2} }^{2} }^{2} }{?} }{?} } ]{?} }{?} \times \frac{?}{?} \times \frac{?}{?} }^{2}$

OK GOT IT..?
