Answer 1

Answer:

${ { \sqrt[1 \sqrt[ \cot( log( log( log( \gamma log( \tan( \cot( log( \gamma \gamma log( ln( log( \gamma \sqrt[0 \sqrt{ \sqrt[ \leqslant < | = |2245 \times \frac{?}{?} | | ]{?} } ]{?} \times \frac{?}{?} ) ) ) ) ) ) ) ) ) ) ) ]{?} ]{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} }^{?} }^{?}$

$> 02 \tan( log( log( log( log( log( log( \beta \beta \beta \beta \beta \gamma \gamma \gamma \gamma \gamma log_{ < 0 \sqrt[?]{?} }(?) ) ) ) ) ) ) ) \times \frac{?}{?}$
