Who understand the task? I mean difinition of "number":
  A number begins with a digit and contains only digits and possibly one point “.”, followed by one or more digits. As in the case of a string a number is the maximal by inclusion sequence of symbols that satisfies the given above requirement.
  I wrote a program:

program Example1;
var a2,a3:byte;
    n,t:integer;
begin
read(n);
t:=n;
a2:=0;
while n mod 2 = 0 do
      begin
           n:=n div 2;
           inc(a2);
      end;
a3:=0;
while n mod 3 = 0 do
      begin
           n:=n div 3;
           inc(a3);
      end;
write(n,'=2^',a2,'*3^',a3,'*',n);
{this program writes a number in n=(2^k)*(3^l)*m form}
{10=2^1*3^0*5}
{36=2^2*3^2*1}
end.

  Could you write HTML-answer?
