Which of the following is power of 3 a) 2345 b) 9875 c) 6504 d) 9833?

Question

pls tell the method

Answer 1

If you mean which of these is a *multiple* of three, then the answer is:
c) 6504.

If a number is divisible by 3, its digits add up to a multiple of 3.
a) 2+3+4+5 = 14
b) 9+8+7+5 = 29
c) 6+5+0+4 = 15 <---
d) 9+8+3+3 = 23

So the answer in this case is c) 6504

Answer 2

If you are asking which of the following numbers are formed by a number raised to the power of 3 - the answer is NONE.

Cube root of 2345 = 13.28559316
Cube root of 9875 = 21.45420214
Cube root of 6504 = 18.66638322
Cube root of 9833 = 21.42374283

What was said in the other answers is only a way to check whether those numbers can be divided by 3.
2+3+4+5=14 no
9+8+7+5=29 no
6+5+0+4=15 yes, it can be divided by three
9+8+3+3=23 no
But if you want the number which is formed by 3 raised to a specific power - the answer is again NONE of those.
6504 = 3 x 2168 = 3 x 3 x 722.6(6)

Answer 3

c)6504
is the correct answer.
I will surely tell u the method but idont know if this is what u were asking for-----
See it is very simple and works only for 3 i just saw the options and found out the sum of the digits of each no. i.e.
a)2345=2+3+4+5=14 not divisible by 3
b)9875=9+8+7+5=29 - -do- -
c)6504=6+5+0+4=15 divisible by 3

Answer 4

2345-5*467 not a multiple so nota power
9875=5*1975=5*5*395=5*5*5*79
no
6504=3*2168=no
9833=not divisible by 3
so none of themis a power of 3
if it is a power of 3 we must be able to put it in the form 3^x
try the div test and prime factorise and see if it can be put in the form of 3^x

Answer 5

None of them are. a) and b) are divisible by five and c) is divisible by to, therefore they could not be powers of 3. d) is not divisible by 3, so it cannot be a power of three either.

Answer 6

none of them are a power of three.... if you mean to say divisible by 3 then its 6504.

Answer 7

none of them

Answer 8

6504

Answer 9

none
