   a)

   (0,125)^4. 8^5

   = [(0,5)^3]^4 . (2^3)^5

   = (0,5)^12 . 2^15

   = 8

   b)

   (-64)^4 :16^4

   = 64^4 :16^4

   = (64:16)^4

   = 4^4

   = 256

   c)

   (-27)^5 :9^8

   = [(-3)^3]^5 : [(3)^2]^8

   = (-3)^15 : 3^16

   = -1/3

   d)

   (-36)^3 – (-6)^6

   = (-36)^3 – (36)^3

   = -93312
