    `@Fun` 

    `h) 50.2 + 100.9 + 10^2 .3`

    `= 100 + 900 + 100 .3`

    `= 1000 + 300` 

    `= 1300` 

    `j) 5^10 : 5`

    `= 5^(10-1)` 

    `= 5^9` 

    `= 1953125` 

    `k) 2^3  . 2^2`

    `= 2^(3+2)` 

    `= 2^5` 

    `= 32` 

    `l) 0.(1+3+5+7+9+…+101).(2+4+6+…100)` 

    `=0` 

    `o) 72.(28-14) + 28.(18-72)` 

    `= 72.14 + 28.(-54)` 

    `= 1008 – 1512`

    `= -504` 

    `p) 28.72 + 28.28` 

    `= 28.(72+28)` 

    `= 28.100` 

    `= 2800`
