Hi Mathematica community,

1)why mathematica is not able to detect that
 i + IntegerPart[Log[2,x]]==iP + IntegerPart[Log[2,xP]] &&
FractionalPart[Log[2,x]]== FractionalPart[Log[2,xP]]
implies i + Log[2,x] == iP + Log[2,xP]?

2)why Reduce is unable to solve this system for the integer variable
iP==i+3&&i + IntegerPart[Log[2,x]]== iP + IntegerPart[Log[2,xP]] &&
 FractionalPart[Log[2,x]]== FractionalPart[Log[2,xP]]?

thank you very much for your help.
