The sum of all the coefficients of the expansion (x+y)^n is 1024 then the greatest coefficient occurs in the r th terms where r is equal to

1.. 6
2.. 5
3.. 4

The last 1 for this thread

Assume R and S are (non-empty) relations in a set A. Which of the following relation given below is false

1. If R and S are transitive, then P U S is not transitive

2. If R ans S are transitive, then R U S is symmetric

1 6 is ans
fr tht convention the reason for more hotness above is convection only .conduction do not explain this phenomena

i just took two sets r=[(1,2)(2,3)(1,3)] s={(a,b)(b,c)(c,a)}rus is transitive
nd u can also think tht all elements of r ,s ll be elements of rus n thus no element ll exists in therus which is non transitive
