  1. 25xx2^4 -3^2 +5^3
    =25xx16-9+125
    =400-9+125
    =391+125
    =516

  2. 25 \times 2^4 -3^2 +5^3
    =25 \times 16-9+125
    =400-9+125
    =391+125
    =516
    2 \times 3^2 +5 \times (2+3^2 )^2
    =2 \times 9+5 \times (2+9)^2
    =18+5 \times 11^2
    =18+5 \times 121
    =18+605
    =623
