find the difference between the the reminder when 7^84 is diveded by 342&344?

• Ans:- 0
  7^84=(7^3)^28=(343)^7
  so (342+1)^7/343= reminder 1
  and 7^84=(7^3)^28=(343)^7/344=(343+1)^7/7 so reminder will be 1
  so difference between the reminder=1-1=0

• I THINK 7^84 =7^4=2401
  2401/342 GIVES REM. 7
  2401/344 GIVES REM. 337
  SO DIFF. 330

• 7^84/342=(7^3)^28/342=(343^28)/342=(1^28)/342=1
  7^84/344=(7^3)^28/344=(343^28)/344=((-1)^28)/344=1
  so d diff is 1-1=0
