d) (-1) =
(2)

5
e) ( 1) =
(3)

f) (3) =
(2)

Answer 1

a) (3/5)² =
     3.3 / 5.5 =  9/25

b) (-4/7)² = 
     -4.-4 / 7.7 = +16/49

c) (-1/5)³ =
     -1.-1.-1 / 5.5.5 = -1/125

d) (-1/2)⁴ =
     -1.-1.-1.-1 / 2.2.2.2 = +1/16

e) (1/3)⁵ =
     1.1.1.1.1 / 3.3.3.3.3 = 1/243

f) (3/2)⁴ =
    3.3.3.3 / 2.2.2.2 = 81/16
