yeh question me hi dal to better rahega

qstn ki value km ho jaegi

anonymous · Answer

(7*3n+4)/7*2n+3
=3n+(4/7)/2n+(3/7)
since 4/7&3/7 are irrational so it is unreducible .

kya hua :)

anonymous · Answer

let me see 1st yaar

anonymous · Answer

If you can make a linear combination of the numerator and denominator equal to 1, then the numbers are relatively prime.

anonymous · Answer

ye kya hai bhai! if u ad irrat. to rat. , u get an irrat. and if you divd irrat by irrat u get irrat till nume. and denom. are not same yeh solution nahi hai, it dsnt prove anything

my response was to 009infinity.

anonymous · Answer

please present me wth solution bt not hints.

anonymous · Answer

U may look for it yourself, it is not too hard to see it in this case....

pahle khud samajh le thik se ek quest ko 
ek quest ko bahut tarike se kar sakte hain

anonymous · Answer

i m talking about this quest

anonymous · Answer

You want s and t such that 

s*(14n +3) + t*(21n +t) = 1  

If you can find such s and t, then the numerator and denominator are relatively prime and so the fraction is irreducible.
