Resposta:
a) √(121/100)+ √(81/25) =11/10+9/5 =29/10
b) √(49/64) - √(625/144)+ √(1/36)- √(16/9)=7/8-25/12+1/6-4/3 = (21-50+4-32)/24 = -57/24
c) √(1/4) - √(1/9) .√(9/16)+ √(49/25) .√(25/36)=1/2-1/3.3/4+7/5.5/6=1/2-3/12+35/30=1/2-1/4+7/6=(6-3+14)/12 = 17/12
d) √(1/4)+ √(1/9)+ √(1/16)- √(1/25)- √(1/36)=1/2+1/3+1/4-1/5-1/6=(30+20+15-12-10)/60=43/60
e) 2/√81-√16/3+2/√25-√36/3=2/9-4/3+2/5-6/3=(10-60+18-90)/45 = -122/45
f) √(4/25)- √(1/9) + √(9/25)- √(4/9)=2/5-1/3+3/5-2/3=(6-5+9-10)/15 = 0/15 = 0
