Explicație pas cu pas:
[tex] \sqrt{2304 : 12} = \sqrt{192} [/tex]
[tex] \sqrt{192} = \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3} = \sqrt{(2 \times 2) \times (2 \times 2) \times (2 \times 2) \times 3} = \\ \\ \sqrt{ {2}^{2} \times {2}^{2} \times {2}^{2} \times 3 } = (2 \times 2 \times 2) \sqrt{3} = 8 \sqrt{3} [/tex]
