d) 6,9367088607594936708860759493671

Explicação passo-a-passo:

a) 3. $\sqrt{5}$ . 4. $\sqrt{2}$=

3 . 2,2360679774997896964091736687313 . 4.1,4142135623730950488016887242097=

6,7082039324993690892275210061939 . 5,6568542494923801952067548968388=

resultado= 37,947331922020551983986722533193

b) $\sqrt{3}$ . $\sqrt{12}$=

1,7320508075688772935274463415059 . 3,4641016151377545870548926830117=

resultado= 6,0000000000000000000000000000001

c) $\sqrt{45}$ : $\sqrt{5}$=

6,7082039324993690892275210061938 : 2,2360679774997896964091736687313=

resultado= 3

d) 20 . $\sqrt{30}$ : 5 . $\sqrt{10}$=

20. 5,48 : 5 . 3,16=

109,60 : 15,80=

resultado= 6,9367088607594936708860759493671
