( a5 · b2 ) / ( a3 · b3 )  

cancelling out the a3 factor from both the numerator and denominator still leaves a factor of a2 in the numerator:

=  ( a2 · b2 ) / ( b3 )  

cancelling out the b2 factor from both the numerator and denominator still leaves a factor of b in the denominator:

=  a2 / b

where  x = 2  and  y = 1 ... 

so  x - y  =  ???
