  1. Lời giải và giải thích chi tiết:
    5^6 ÷ 5^4 + 2^3 . 2^2 -225 ÷ 15^2
    =5^6 ÷ 5^4 + 2^3 . 2^2 – 15^2 ÷ 15^2
    =5^(6-4)+2^(3+2) – 15^(2-2)
    =5^2+2^5-1
    =25+32-1
    =56

  2. 5^6 :  5^4 + 2^3 . 2^2 – 225 : 15^2
     =5^{6-4} + 2^{3+2} – 15^2 : 15^2
    = 5^2 + 2^5 – 1
    =25 + 32 – 1
    =56
