Answer 1

a) -17/50

b) 1

c) 1/3

d) 1/103/108

e) 1/56/225

Answer 2

a)1/2*1/25-(3/5)²= 1/50- 9/25= 1/50-18/50=-17/50
b)2*(1/3)2 + 7/9= 2* 1/9+ 7/9= 1
c)4/3*(-1/2)2-2 0 (do zera)= 4/3* 1/4-1=-2/3
d) -(2/3)3+(-3/2)2= -8/27+ 9/4= -32/108+ 243/108=211/108=1  103/108
e) (3/5)2-2*(1/2)3:2 1/4 - (-1)3= 9/25-1/4 * 4/9 +1= 81/225-25/225 +1=1 56/225
