1. a) 5^6 : 5^4 + 2^3 . 2^2 – 1^2017

   = 5^2 + 8 . 4 – 1

   = 25 + 32 – 1

   = 57 – 1

   = 56

   ———–

   b) [36 . 4 – 4 . (82 – 7 . 11)^2] : 4 – 2016^0

   = [36 . 4 – 4 . (82 – 77)^2] : 4 – 1

   = (36 . 4 – 4 . 5^2] : 4 – 1

   = (144 – 4 . 25) : 4 – 1

   = (144 – 100) : 4 – 1

   = 44 : 4 – 1

   = 11 – 1

   = 10

   • Áp dụng: a^0 = 1
