Answer 1

43-36=7
37 do potęgi 2 = 1369
23* 10 = 230
17* 10 do potęgi 2 = 17* 100= 1700
1 i  7/10 + 16/15 * 3/8 = 1 i 7/10 + 8/10 = 1 i 15/10 =2 i 5/10 = 2 i 1/2
1,2 - 0,12 = 1,08
(1 i 3/5 + 2 i 1/5 ) : 19/3 = 3 i 4/5 * 3/19 = 19/5 * 3/19 = 3/5

Answer 2

43 - 6*6 = 43 - 36 = 7

(43-6)² = 37² = 1369

23 * (13-3) = 23 * 10 = 230

17 * (20:2)² = 17 * 10² = 17 * 100 = 1700

1 7/10 + 1 1/15 : 2 2/3 = 17/10 + 16/15 : 8/3 = 17/10 + 16/15 * 3/8 = 17/10 + 2/5 = 17/10 + 4/10 = 21/10 = 2,1

1,2 - 0,8 * 0,15 = 1,2 - 0,12 = 1,08

(1 3/5 + 2 2/10) : 6 1/3 = (16/10 + 22/10) : 6 1/3 = 38/10 : 19/3 = 38/10 * 3/19 = 6/10 = 0,6

Mam nadzieje, że pomogłem :)
