Answer 1

A) (1/2)^5        1/32
    ----------  =  ----------- = 1/32 * 3 = 3/32
    (1/3)^1         1/3


b) (1/4)^2         1/16   
     ----------  =  -------- = 1/16*512 = 512/16= 32
     (1/8)^3      1/512 


c) 1/2 + 1/6 = 3/6 + 1/6 = 4/6 = 2/3

d) (1/2)^2 + (1/3)^2 = 1/4 + 1/9 = 9/36 + 4/36 = 13/36

e) (1/2)^5 * (1/4)^2 = 1/32 * 1/16 = 1/512
