use reminder theorem. here it is given as 50^51^52. but consider it as 50*51*52 so when it is divided by 11 it gives -ve remainder of (-5)*(-4)*(-3) = 20*(-3) again use remainder theorem so now it becomes (-2)*(-3) = 6. so the ans is 6. But note that it is valid only in case of consecutive no. i.e 50,51,52 or 34,35,36 but not in case when it is given 30^72^87 etc

answer is 6
51^52 will give a no with unit digit 1
50^some no with unit digit 1=((50)^some no having 0 unit digit)*50
=some no with 0 unit digit *50
50 divided by 11 gives 6.
