Por favor gente eu só tenho mais 5 minutos pra entregar...

Answer 1

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
