Answer:

$yy log( log( log( \sqrt{yy \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \sqrt[ \frac{ \frac{ \frac{ \frac{ { { { { { { { { { \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \frac{ \frac{ { { {y \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{?} } } } } } } } } } } } } } } } } }^{2} }^{2} }^{2} }{?} }{?} } } } } } }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} \times \frac{?}{?} }{?} }{?} }{?} }{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} ]{?} ]{?} ]{?} ]{?} ]{?} ]{?} ]{?} ]{?} ]{?} ]{?} } ) ) )$
