what will be last two digit of 4761^235
Read Solution (Total 17)
-
- unit place of 4761^235=1
10th place of 4761^235=(10th place of 4761)*(unit place of 235)=6*5=0
so,last two digit of 4761^235=01 - 11 years agoHelpfull: Yes(52) No(0)
- any number ending with with 1
for example (XX61)^n , n---->be anything
unit digit will always be 1
and for the tens digit :multiply tens digit(of the number) with unit digit of power
i.e. tens digit of number--> 6
and unit digit of power --> 5
so 6*5=30
i.e. nothing but 0 @tens place
so answer =01 - 11 years agoHelpfull: Yes(14) No(1)

- 4761^235 last 2 digit depend on 61
6 - 11 years agoHelpfull: Yes(0) No(5)
- check the cyclicity of 61 its 5 and the 5th iteration is 01
ans is 01 - 11 years agoHelpfull: Yes(0) No(0)
- lasrt digit will be 1 as unit digit is 1
tens digit i will be 0 as (tens digit of base * multiply with unit digit of expo)=5*6=30 so 0 is take
hence 01 is answer

- 4761's unit digit=1 and 1^5=1
and 10th digit of 4761 is 6 and 6^5=30
so last two digit will be 01 - 11 years agoHelpfull: Yes(0) No(0)
- first place of 4761^235 from right to left is 1
second place of 4761^235 from right to left is=(second place of 4761 from right to left is)*(unit place of 235 from right to left is)=6*5=0
last two digit of 4761^235=01 - 11 years agoHelpfull: Yes(0) No(0)
- ans is 01 as taking last two digits from 4761.((61)^5)^47) as 235=47 * 5 .61^5=01 now (01)^47=01.

- 235/4 remainder=3 so 4761^3= last two digit =31
- 11 years agoHelpfull: Yes(0) No(2)
- ans 35, (4760+1)235=118600+235
- 11 years agoHelpfull: Yes(0) No(3)
- ANS=61
please find the cycle of 61.you will get it is 6.
235/6 leaves the reminder 1.so last two digit will be equivalent to 61^1
that is 61
