a little more space b/w the letters will make this soln. perfect.....:)

Sorry for that, I am new to tying here :)

@Ahmed Taha – no problem :)

Thanks guys! :)

is this a question in a Philippine Math Olympiad?

Yes! :) On the QS.

[-1/2,4] You should be able to work out how I got this. HINT: what can you do since the bases are reciprocals?

yeah...answer...[-1/2,4]...agreed...:)
