Answer 1

a) 308,6X0,5+8,3X4,5-3,5X(72-71,4)=
    154,3+37,35-3,5X0,6=
     154,3+37,35-2,1=
    154,3+35,25=189,55

b) 101,1X(0,37+1,53)-(134,6-92,7)X0,031=
    101,1X1,9-41,9X0,031=
    192,09-1,29=190,8

c) 125,61-(3,67-2,38)X(3,67+2,38)-40,49=
    125,61-1,29X6,05-40,49=
    125,61-7,80-40,49=77,32

d) 17,4X0,5-(9,8+1,4)X0,1+0,3X(24,3-18,8)=
     8,7-11,2X0,1+0,3X5,5=
     8,7-1,12+1,65=9,23
