Answer 1

Answer:

${y) { \frac{ {y563 = 1563. { \frac{ \sqrt[ \sqrt[?]{?} ]{?} }{?} }^{?} }^{?} }{?} }^{2} }^{?} \times \frac{?}{?} 4 { \frac{ {?}^{?} }{?} }^{2} { {xy}^{2} }^{?} 5611 { \sqrt[ |?| ]{?} }^{?} \times \frac{?}{?} \cos(?) \tan(?) \cot(?) \tan(?) \sec(?) \csc(?) \alpha \alpha \beta \gamma e\pi \infty \alpha ln( log( log_{\% \cot(?) }(?) ) ) e \sec( \sec( \infty \gamma ) )$
