Answer 1

Explicație pas cu pas:

$a) \: \frac{ \sqrt{625} }{ \sqrt{25} } = \sqrt{ \frac{625}{25} } = \sqrt{25} = 5 \\ b) \: \sqrt{50} \times \sqrt{4.5} = \sqrt{50 \times 4.5} = \sqrt{225} = 15 \\ c) \: \sqrt{ {5}^{2} \times {3}^{2} \times 7 {}^{2} \times {11}^{2} } = \sqrt{ {5}^{2} } + \sqrt{ {7}^{2} } + \sqrt{ {3}^{2} } + \sqrt{ {11}^{2} } \\ = 5 + 3 + 7 + 11 = 26$
