Answer 1

6-2 = 1/6*6 = 1/36

3-2 = 1/3*3 = 1/9

2-5 = 1/2*2*2*2*2 = 1/32

7-3 = 1/7*7*7 = 1/343

11-2 = 1/11*11 = 1/121

20-3 = 1/20*20*20 = 1/8000

300-2 = 1/300*300 = 1/90000

19-1 = 1/19

2-1 = 1/2

(-1)5 = 1

2 3 = 8

(-4) 3 = -64

3-2 = 1/9

4-2 * 6-1 = 1/16 * 1/6 = 1/96

2-3*10-2 = 1/8 *1/100 = 1/800

6-2 + 9-1 = 1/36 + 1/9 = 1/36 + 1/36 = 5/36

1.21 + 0.2-2 = 1.21 + 2.5 = 3.61
