Long Number Power Calculate using Log method c++

Calculate:
                     
                     Base1 ^ power1 = Base2 ^ power2
                  Base1 ^ power1 < Base2 ^ power2
                  Base1 ^ power1 > Base2 ^ power2


Example:

Base1 = 2, power1  =  3, Base2 =  4, Power2 =  2
Output: "Second is Big";

Base1 = 2, power1  =  2, Base2 =  3, Power2 =  1
Output: "First is Big";

Base1 = 2, power1  =  4, Base2 =  4, Power2 =  2
Output: "Both are Same";


Note: You need to use the same base (Base1 = Decimal && Base2 = Decimal ) or  use Others base.
