Remember this 3 lines 1.Last Digit of a num =0,1,5,6 ; Unit Digit will be 0,1,5,6 (For any power) 2.If Last Digit of a num =4,9 and Power is odd ; Unit digit will be 4,9 ; if Power is even Unit digit will be 6,1 3.if Last digit of a num =2,3,7,8 ; Devide the power by 4, if Remainder=0 ; Unit Digit will be 6 for 2 & 8 ; 1 for 3 & 7 ; if R !=0 Unit Digit will be (last Digit)^R ;

Dear ma'am please pinned the comment about when l = 3,7 or 9 the unit digit is 1 instead of 0 👍 For example : 143^124 By dividing 124 by 4 the remainder is 0. In this case we can take 3⁴=81. So the unit digit is 1. 🙏
