Question

1. Scoateţi factorii de sub radical: a) √96; √48; √√72; √56; √84; √108; √162; √192; √150; √147;​

Answer 1

Răspuns:

$\sqrt{96} = \sqrt{16 \times 6} = 4 \sqrt{6} \\ \\ \sqrt{48} = \sqrt{16 \times 3} = 4 \sqrt{3} \\ \\ \sqrt{72} = \sqrt{36 \times 2} = 6 \\ \\ \sqrt{56} = \sqrt{4 \times 14} = 2 \sqrt{14} \\ \\ \sqrt{84} = \sqrt{4 \times 21} = 2 \sqrt{21} \\ \\ \sqrt{108} = \sqrt{36 \times 3} = 6 \sqrt{3} \\ \\ \sqrt{162} = \sqrt{81 \times 2} = 9 \sqrt{2} \\ \\ \sqrt{192} = \sqrt{64 \times 3} = 8 \sqrt{3} \\ \\ \sqrt{150} = \sqrt{25 \times 6} = 5 \sqrt{6} \\ \\ \sqrt{147} = \sqrt{49 \times 3} = 7 \sqrt{3}$
