find n if (2^228/2^n)=512

• 2^228=512*2^n
  2^228=2^9*2^n
  2^228=2^(9+n)
  228=9+n
  n=228-9
  n=219

• (2^228/2^n) = 512 = 2^9
  => 2^228 = 2^n+9
  => n+9 = 228
  => n = 219.
  therefore, the required value of n is 219.

• Since,512=2^9
  So,by cross multiplication..2^9 * 2^n=2^(9+n)
  and left side is:2^228.
  so,becauz of same base both side...the power goes equal..so 9+n=228
  n=228-9=219..Ans

• ans= n-1+n-2=2n-3.
  First detective will call all other detectives : Eg: 1st detective calls 2nd,3rd,....nth, so n-1 calls, by this 1st and the nth detective knows all the information. Now 1st detective, since he knows all the information will call the n-2 detectives and share the info with them. hence n-1+n-2 =2n-3 calls.

• (2^228/2^n)=512
  By using reverse logic,we can solve it
  formula:a^m*a^n=a^(m+n)
  2^9=512
  228-9=219
  so 2^n=2^219
  answer:n=219

• 2^228/2^n we can write this as 2^(228-n) which should give the result as 512.
  and 512 is 2^9 .
  so 228-n=9
  => n=228-9
  => n=219 .
  so we get 2^228/2^219 result is 512 .
