Answer 1

Răspuns:

$\sqrt{14 + 7 \sqrt{25} } - \sqrt{ {26}^{2} - {24}^{2} } + 10 \sqrt{0.09} = \\ = \sqrt{14 + 7 \times 5} - \sqrt{(26 + 24) \times (26 - 24) } + 10 \sqrt{ \frac{9}{100} } = \\ = \sqrt{14 + 35} - \sqrt{50 \times2 } + 10 \times \frac{ \sqrt{9} }{ \sqrt{100} } = \\ = \sqrt{49} - \sqrt{100} + 10 \times \frac{3}{10} = 7 - 10 + 3 = - 3 + 3 = 0$
