[tex] \sqrt{360} = \sqrt{6^{2} \times 10 } = \sqrt{6 {}^{2} } \times \sqrt{10} = 6 \sqrt{10} [/tex]
[tex] \sqrt{2400} = \sqrt{20 ^{2} \times 6 } = \sqrt{20 ^{2} } \times \sqrt{6} = 20 \sqrt{6} [/tex]
[tex] \sqrt{1280} = \sqrt{16 ^{2} \times 5 } = \sqrt{16 ^{2} } \times \sqrt{5} = 16 \sqrt{5} [/tex]
Sper că te-am ajutat! :-)
