Does this question has any chance of coming in 10th term 1 ???
No it will not come... its not in N.C.E.R.T
This problem is quite confusing..
Jsunil is the best
i think it will . Because t is a good logical question
No ... Bcoz this sums are useful only in case of competive exams not for any ncert based exam papers ... If u r gonna have any exam like JEE then this question is very useful, according to me!!!
What happens in the adding 1 and 2 step
ie how did root n+1 arrive
I thinkit will come in the exam coz i hve sen this questions in many sample papers
Why doesn't √(n-1)+ √(n+1) being rational directly imply that both √(n-1) and √(n+1) are rational? Is there any condition where addition of two pure irrationals results in a rational number?
