If a N= a n: n N and b N c N=d N , where a, b, c N and b, c are coprime, then

Options

  1. Ab=c d
  2. Bc=b d
  3. Cd=b c
  4. DNone of these

Correct answer

C. d=b c

Step-by-step solution

We have, b N= b n: n N , c I N= c n: n N and d N= d n: n N Also, b c b N c N =d N [given] array ll & b c b N c N or b c d D & b c=d array [as b and c are coprime]
