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
- Ab=c d
- Bc=b d
- Cd=b c
- 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]
