Answer 2

Resposta:

Explicação passo-a-passo:

A)

= 10/(2 - \/2) . (2+\/2)/(2+\/2)

= 10.(2+\/2)/(2-\/2).(2+\/2)

= 10.(2+\/2)/(4+2\/2-2\/2-2)

= 10.(2+\/2)/2

= 5.(2+\/2)

R. : = 10 + 5\/2

_________

B)

= 3/(\/5 + \/3) . (\/5-\/3)/(\/5-\/3)

= 3.(\/5-\/3)/(\/5+\/3).(\/5-\/3)

= 3.(\/5+\/3)/(\/5.\/5-\/3.\/5+\/3.\/5-3)

= 3.(\/5+\/3)/(5-3)

= 3(\/5+\/3)/2

R.: = (3\/5+3\/3)/2

__________

C)

= \/2/ (\/3 - 1) .(\/3+1).(\/3+1)

= \/2.(\/3+1)/(\/3-1).(\/3+1)

= \/2.(\/3+1)/(3+\/3-\/3-1)

= \/2.(\/3 + 1)/2

R.: = (\/6 + \/2)/2

_____________

D)

= (\/11 + 1)/(\/11 - 1) . (\/11 +1)/(\/11 +1)

= (\/11 + 1).(\/11 + 1)/ (\/11 - 1).(\/11 + 1)

= (11 + \/11 + \/11 + 1)/(11 + \/11 - \/11 - 1)

= (12 + 2\/11)/10

= 2.(6+\/11)/10 (:2)/(:2)

R.: = (6 + \/11)/5
