    Re: number system

    Hello, geniusgarvil!

    Where did this problem come from?


    \text{There is a number }2^n.\;\text{When its digits are reversed it, becomes }2^m.
    \text{Find the least possible value of }n.

    We want a power-of-two which is the reversal of a power-of-two.

    Without initiating a computer search,
    . . it seems that only answers are one-digit values.

    Re: number system

    I am not getting this , you should discuss problem with good theory so I can give a better solution. in my opinion power of integer shows it's multiple and it's a short form of any large number most probably used in algebra, linear equation and differential equation problems.how to do pre algebra

    Re: number system

    This seems like quite the silly problem because n=0 works just fine
