Zad 1
Odpowiedź C, ponieważ:
[tex] \sqrt{72} = \sqrt{8 \times 9} = 3 \sqrt{8} = 3 \sqrt{2 \times 4} = 3 \times 2 \sqrt{2} = 6 \sqrt{2} [/tex]
Zad 2.
[tex]4 \sqrt{6} = \sqrt{6 \times 16} = \sqrt{96} [/tex]
[tex]5 \sqrt{7} = \sqrt{7 \times 25} = \sqrt{175} [/tex]
[tex]6 \sqrt{5} = \sqrt{5 \times 36} = \sqrt{180} [/tex]
Najwieksza liczba to
[tex]6 \sqrt{5} [/tex]
