well, see let us do it like this .. for each term we find out the condition on x and then try to get intersection of all ..
 
 x - 3 > 0     .. (1)
 x - 1 > 0     .. (2)
 
 also, - logx-3(x-1) > 0  ( since it is in the sq rt sign )
 
Now, from (1) and (2) we know that x > 3
 
we want logx-3(x-1) <  0 , so now x - 1 > 2 , so x - 3 < 1 is the only way left to make it less than 0
 
thus we get x < 4   ... (3)
 
combining (1) and (3) we get,
 
                                     3 < x < 4          ... (4)
 
Now the term -x2+2x+8 > 0
 
or,         9 - (x - 1)2 > 0
 
which means 3 > x - 1 > -3
 
or,    4 > x > - 2                                     .. (5)
 
From (4) and (5) we get
 
 3 < x < 4    .. Ans
 
 
cheers
