Answer 1

a ) (20:4)+(6:3)+(3x4-9x1)2
(5)+(2)+(12-9)2
7+3+2
11

Answer 2

a) 20/4+6/3+(3.4-9.1)2
5+2+(3.-5)2
7+(-15)2
7+(-30)=-23
b) [14+(4.5-3.6)3]-18/9
14+(20-18)3-2
14+2(3)-2
14+6-2=18
c)(3.6-7.2)3+(16/8-12/12)6
(18-14)3+(2-1)6
4(3)+1(6)
12+6=18
d)8+63/(14/7+6°)2+2.10
8+(63/2+1)2+20
8+(63/3)2+20
8+21.2+20
8+42+20=70
