`{:[( 1,1+p,1+p+q),( 2,3+2p,1+3p+2q),( 3,6+3p,1+6p+3q)]:}=1`

If (p, 2p) , (2p, 3p) and ( 3 , 1) are collinear then p = ........

If f={(1,a), (2, b), (1, b), (3,c), (1,c)}, g=(a, p), (b,r), (c,q), (c,p)} , then (gof)^(-1)=

The arrangment of the following distances between the points in ascending order is (A) P(0, 0), Q(1, 1) " "(B) P(0, 1), Q(0, 5)" "(C) P(3, 0), Q(8, 0)" "(D) P(0, 0), Q(-2, -2)

If |x| lt 1 then (d)/(dx ) [1+ (px)/(q) + (p (p+q))/(2 !)((x)/(q))^(2) + (p(p+q) (p+ 2q))/(3!) ((x )/(q))+...]=

If A = |{:(p,q,r),(r,p,q),(q,r,p):}|and A A ^(T) = I "then" p^(3) + q^(3) + r^(3) =

{:(,"List - I",,"List - II"),((1),~(~p) harr "p is " ,(a),(~p vv ~q)),((2),(p ^^ q)^^ (~(p vv q))" is ",(b),"a tautology"),((3),~(p ^^ q)-=,(c ),(~p ^^ ~q)),(,,(d),"a contradiction"):} The correct match is :

For three vectors p, q and r, if r = 3p + 4q and 2r = p - 3q, then

The electronic configuration of four elements L, P, Q and R are given below. L- 1s^2 2s^2 2p^4 P- 1s^2 2s^2 2p^6 3s^1 Q- 1^2 2s^2 2p^6 3s^2 3p^5 R- 1s^2 2s^2 2p^6 3s^2 . Which of the following are correct compounds formed by these elements?
