Question

xyxxyx÷xyx-abab÷ab= cu bara deasupra

Answer 1

xyxxyx=100000x+10000y+1000x+100x+10y+x
           =101101x+10010y
xyx=100x+10y+x
     =101x+10y

(101101x:10010y):(101x+10y)=
=101101x:101x+10010y:10y
=1001x+1001y
=1001(x+y)

abab=1000a+100b+10a+b
         =1010a+101b
         =101(10a+b)
         =101 ab (cu bara deasupra)

=1001(x+y)-101(10a+b)
