срочно даю 30 БАЛОВ!!!!​

Answer 1

Ответ:

1) 2 × √16 + 3 × √25 - 4 × √0,04 = 2 × 4 + 3 × 5 - 4√1/25 = 8 + 15 - 4 × 1/5 = 23 - 4/5 = 111/5

2) √49 × √100 + 3 × √65 - 2,1 × √169 = 7 × 10 + 3 × 8 - 2,1 × 13 = 70 + 24 - 27,3 = 66, 7

3) 0,1 × √81 + 8 × √121 - 19,45 × √9 = 0,1 × 9 + 8 × 11 - 19,45 × 3 = 0,9 + 88 - 58,35 = 30, 55

4) 12 × √196 - 27 × √16 - 15 × √2,56 = 12 × 14 - 27 × 4 - 15 × √64/25 = 168 - 108 -15 × 8/5 = 168 - 108 - 3 × 8 = 168 - 108 - 24 = 36

Удачи!
