Answer 1

$5^{7}+4^{9}+3^{8}+5^{-2}+4^{-3}+(-5^{3})+88^{4}= 78125+262144+6561+\frac{1}{5^2}+\frac{1}{4^3}+(-125)+59969536= 78125+262144+6561+[tex]340269+6561+[tex]346830+\frac{1}{25}+\frac{1}{64}+(-125)+59969636= \frac{346830}{1}+\frac{1}{25}+\frac{1}{64}+(-125)+59969636= [tex] \frac{8670751}{25}+\frac{1}{64}=\frac{554928064}{1600}+\frac{25}{1600}=\frac{554928089}{1600}$
