    Re: Digit sum

    2^1999=(2^2000)/2

    5^2001=(5^2000)*5

    lhs={(2*5)^2000}*5/2

    (10^2000)*2.5
    {(10^2)^1000}*2.5

    (100^1000)*2.5

    5^2001=(5^2000)*5

    lhs={(2*5)^2000}*5/2=(10^2)^1000*2.5=(100^1000)*2.5=(1 followed by 20 zeroes)*2.5=25 followed by 19 zeroes=>this gives sum of digits=2+5=7
