Explicație pas cu pas:
Salutare!
(A)
[tex]\bf \sqrt{50} :\sqrt{5} =\sqrt{50:5}=\boxed{\bf\sqrt{10} }[/tex]
(B)
[tex]\bf \sqrt{15} :(-\sqrt{3}) =- \sqrt{15} :\sqrt{3}= -\sqrt{15:3}=\boxed{\bf-\sqrt{3} }[/tex]
(C)
[tex]\bf -\sqrt{35} :(-\sqrt{7}) =\sqrt{35} :\sqrt{7}= \sqrt{35:7}=\boxed{\bf\sqrt{5} }[/tex]
(D)
[tex]\bf 4\sqrt{21} :\sqrt{7} = 4\sqrt{21:7}= \boxed{\bf 4\sqrt{3} }[/tex]
(E)
[tex]\bf (-9\sqrt{14}) :\sqrt{2} = -9\sqrt{14}:\sqrt{2} =-9\sqrt{14:2}= \boxed{\bf -9\sqrt{7} }[/tex]
(F)
[tex]\bf (16\sqrt{42}) :(-8\sqrt{7}) = -16\sqrt{42}:8\sqrt{7} = -16:8\sqrt{42:7} = \boxed{\bf -2\sqrt{6} }[/tex]
