which of the following is power of 3?
a.2345
b.9875
c.6504
d.9833

• option c is the right answer because 6+5+0+4=15 which is divisible by 3.
  but in option a, 2+3+4+5=14 ,not divisible by 3
  in option b, 9+8+7+5=29 ,not divisible by 3
  in option d, 9+8+3+3+=23, not divisible by 3,

• Option c is write bcz 6504 is divisible by 3 (or)
  Sum of digits 6+5+0+4=15 which is divisible by3
  Other options are not divisible by 3
• 8 years agoHelpfull: Yes(0) No(0)
• Ans: Option c-6504
  Because 6504 is divisible by 3
• 8 years agoHelpfull: Yes(0) No(0)
• Since only option (c) 6504 adds upto 6+5+0+4= 15 is divisible by 3 therefore only 6504 is a power of 3.
• 8 years agoHelpfull: Yes(0) No(0)
• 2345/3 is not divisible by 3 similarly b and d also since option c is divisible by 3 so it is correct
• 8 years agoHelpfull: Yes(0) No(0)
• If any number is in power of 3, then it should also be divided by 3... if we see options only c.6504 is divisible by 3... soo answer is C.6504

• Sorry guys you all are wrong
  correct ans is D)9833.
  we know that 3^1=3,3^2=9,3^3=27,3^4=81,3^5=243 and so on...
  here see last digit 1,3,9,7 only it again repeated..
  and in option there is only one that has last digit 3

• First check divisible to 3.
  2+3+4+5=14 not divisible ,9+8+7+5=29 not divisible, 6+5+0+4=15 divisible, 9+8+3+3=23 not divisible
  Here only one Number is divisible 6504 hence
  Ans c)

• last digit of 3^1=3, 3^2=9, 3^3= 7, 3^4= 1, 3^5= 3, 3^6=9 clearly we can see that we can never get 5 r 4 in the last digit with the power f 3 so d is the right answer
