Квадратный корень. 8​

Answer 1

Объяснение:

$\sqrt{50} \times \sqrt{ \frac{70}{13} } \times \sqrt{ \frac{65}{63} } \times \sqrt{9} = \sqrt{50 \times \frac{70}{13} \times \frac{65}{63} \times 9} = \sqrt{ \frac{50}{1} \times \frac{70}{13} \times \frac{65}{63} \times \frac{9}{1} } = \sqrt{ \frac{50 \times 10 \times 5}{1} } = \sqrt{2500} = 50$
