    16^5.23-2^18.5-8^6.7
    =(2^4)^5.23-2^18.5-(2^3)^6.7
    =2^20 .23-[2^18 .(5+7)]
    =2^20 .23-[2^18 .12]
    =2^20 .23-2^18 .2^2 .3
    =2^20 .23-2^20 .3
    =2^20 .(23-3)
    =2^20 .20

    =2^20.23-2^18.5-2^18.7
    =2^20.23-2^18.(5+7)
    =2^20.23-2^18.12
    =2^20.23-2^18.4.3
    =2^20.23-2^18.2^2.3
    =2^20.23-2^20.3
    =2^20.(23-3)
    =2^20.20(số lớn quá nên để yên)
