Question

Explicati-mi radicalul va rog, sau cel putin bazele acestuia.​

Answer 1

$\boxed{\sqrt{ {a}^{2} } = a}$

Exemple:

$\sqrt{49} = \sqrt{ {7}^{2} } = 7$

$\sqrt{25} = \sqrt{ {5}^{2} } = 5$

$\sqrt{36} = \sqrt{ {6}^{2} } = 6$

$\sqrt{1} = 1$

$\sqrt{100} = \sqrt{ {10}^{2} } = 10$

$\sqrt{16} = \sqrt{ {4}^{2} } = 4$

$\sqrt{9} = \sqrt{ {3}^{2} } = 3$

$\sqrt{12} = \sqrt{4 \times 3} = \sqrt{ {2}^{2} \times 3} = 2 \sqrt{3}$

$\sqrt{8} = \sqrt{ {2}^{2} \times 2 } = 2 \sqrt{2}$

${ \sqrt{50} } = \sqrt{5 \times 10} = \sqrt{5 \times 2 \times 5} = \sqrt{ {5}^{2} \times 2 } = 5 \sqrt{2}$
