to find the unit digit of the equation we will have to divide it by 10.(213*212*347*468*778)/10
=(3*2*7*8*8)/10
so, the remainder will be 8=unit digit

8 because when if we multiply only d unit's digits of the numbers then we automatically get that d last digit will be 8
8*8 last digi is 4 then 4 s multiplied with 7 then the last digit will be 8 then again it is multiplied with 2 last digit will be 6 and when 6 will be muliplied by 3 last digit will be 8
