Ex 5, 6 va rog frumos e urgent dau coroană ​

Answer 1

Răspuns:

5.

$\sqrt{172} = 2 \sqrt{43}$

$\sqrt{180} = 6 \sqrt{5}$

$\sqrt{90} = 3 \sqrt{10}$

$\sqrt{297} = 3 \sqrt{33}$

$\sqrt{1125} = 15 \sqrt{5}$

$\sqrt{363} = 11 \sqrt{ 3}$

$\sqrt{288} = 12 \sqrt{2}$

6.

$6 \sqrt{3} = \sqrt{6^{2} \times 3 } = \sqrt{36 \times 3} = \sqrt{108}$

$10 \sqrt{5} = \sqrt{10^{2} \times 5} = \sqrt{100 \times 5} = \sqrt{500}$

$13 \sqrt{6} = \sqrt{ {13}^{2} \times 6} = \sqrt{169 \times 6} = \sqrt{1014}$

$9 \sqrt{2} = \sqrt{ { 9}^{2} \times 2 } = \sqrt{81 \times 2} = \sqrt{162}$

$8 \sqrt{7} = \sqrt{ {8}^{2} \times 7} = \sqrt{64 \times 7} = \sqrt{448}$

$7 \sqrt{5} = \sqrt{ {7}^{2} \times 5} = \sqrt{49 \times 5} = \sqrt{245}$

$12 \sqrt{3} = \sqrt{ {12}^{2} \times 3 } = \sqrt{144 \times 3} = \sqrt{432}$
