A=(2. 5^22 -9.5^11)/(5^80)
A=(5^21. (2-9.5))/5^80
A=(2-45)/5^59
B=(5.3.7^15-5.19.7^14)/(7^16+3.7^15)
B=(7^14.(5.3.7 -5.19))/(7^14. (7^2+3.7)
B=(5.3.7 -5.19)/(7^2+3.7)
B=(105-95)/(49+ 21)
B=10/70
B=1/7
C=(2^10 .3^8 -2. 3^9 .2^9)/(2^10 .3^8 +3^8 .2^8 .2^2. 5
C=(2^10 .3^8 -3^9 .2^10)/(2^10 .3^8 +3^8 .2^10. 5)
C=(2^10. (3^8- 3^9))/(2^10. (3^8 + 3^8 .5)
C=(3^8-3^9)/(3^8+ 3^8.5)
C=(3^8. (1-3))/(3^8. (1+1.5)
C=(1-3)/(1+5)
C=-2/6
C=-1/3
