a)
[tex] \sqrt{44} = \sqrt{4} \times \sqrt{11} = 2 \times 3.317[/tex]
Fałsz
b)
[tex] \sqrt{1100} = \sqrt{11} \times \sqrt{100} = 10 \times 3.317[/tex]
Fałsz
c)
[tex] \sqrt{9 + 11} = \sqrt{20} = \sqrt{4 \times 5} = 2 \sqrt{5} [/tex]
Fałsz
d)
[tex] \sqrt{99} = \sqrt{9} \times \sqrt{11} = 3 \times 3.317[/tex]
