Answer 1

19)

$\frac{8^{20} }{8^{18} } + \frac{5^{14} }{5^{13} } +\frac{2^{6} }{4}$

$8^{2} +5^{1} + \frac{2^{6} }{2^{2} }$

$64+5+ 2^{4} =85$

20)

$\frac{3^{10} . 5^{7} . 2^{3} .2^{3}.2^{3}.1^{20} .5^{1} .5^{1} }{2^{9}.5^{9} .3^{8} }+1$

$\frac{3^{10} . 5^{9} . 2^{9} .1^{20} }{2^{9}.5^{9} .3^{8} } +1$

$3^{2} .1.1+1=10$
