Answer 1

Ответ: 3/16, 121, 49, 16, 25, 1/343, 8, 4, - 1/2,7 (или - 10/27), 15

Объяснение:

Answer 2

Объяснение:

1)√9/16=3/4

2)11²=121

3)2√121+3√81=2*11+3*9=22+27=49

4)√256=16

5)√625=25

6)1/49√49=1/49*7=1/7

7)6+0,25×√64=6+0,25*8=6+2=8

8)1/2√144-2=1/2*12-2=6-2=4

9)-1/3√0,81=-10/27

10)17-√2²=17-2=15

Answer 3

1) √9/16 = √(9)/√(16) = 3/4

2) 11² = 11 * 11 = 121

3) 2√121 + 3√81 = 2 * √(11²) + 3 * √(9) = 2 * 11 + 3 * 3 = 22 + 9 = 31

4) √256 = 16

5) √625 = 25

6) 1/49√49 = 1/49 * 7 = 1/7

7) 6 + 0,25 × √64 = 6 + 0,25 * 8 = 6 + 2 = 8

8) 1/2√144 - 2 = 1/2 * 12 - 2 = 6 - 2 = 4

9) -1/3√0,81 = -1/3 * 0,9 = -0,3

10) 17 - √2² = 17 - 2 = 15
