3243^8897+6547^2314... what is the last two digits?
Read Solution (Total 21)
-
- 52 is the ans.the cycle of 43(43,49,07,01).so remainder of 8897/4 will give remainder as 1 then 43 is taken.the cycle of 47(47,09,23,81) so the remainder of 2314/4 gives 2 as the remainder 09 is taken so sumof 43 and 09 is 52

- for 43===> 43 as BISWAJIT////// & 47square=09, thus (09)^(1157).....power cycle of 09 (09,81,29,61,49,41,61,21,89,01).... seventh if 69.... thus 69+43=12

- 19 is the ans. power cycle of 43(43,49,07,01) is 4 . so 8897/4 will give remainder as 1 then 43 is taken .For 74 the power cycle is 2(76,24) so 2314/2 gives remainder 0 so 76 is taken 76+43=119 last two digits are 19

- 4^7,3^7 last 2 digit unit places is=47
7^4,4^4 last 2 digit unit places is=61
sum=47+61=108
so,last 2 digits = 08 - 10 years agoHelpfull: Yes(0) No(0)
