If `A={a,b}`, then all possible ordered paris are (a,a) (b,b) (a,b) (b,a).

If A={a,b,c} and B={1,2,3,4} . Then all possible ordered pairs such that in each ordered pair the first component is an element of set A and second component is an element of set B are obtained by pairing each element from set A with each element form set B. This can be done by the following scheme:

If a ,b in {1,2,3,4} and a x^2+b x+1=0 has real roots then number of possible ordered pairs of (a , b) is (a)6(b) 7 (c) 10 (d) 12

If a ,b , in {1,2,3,4} and ax^2+b x+1=0 has real roots then a. ageqb b. alt=b c. number of possible ordered pairs of (a ,b) is7 d. 3b-2ageq0

If a,b, and c are positive integers such that a+b+c le8 , the number of possible values of the ordered triplet (a,b,c) is

If a, b, c are three natural numbers in AP such that a + b + c=21 and if possible number of ordered triplet (a, b, c) is lambda , then the value of (lambda -5) is

If a, b and c represent the lengths of sides of a triangle then the possible integeral value of (a)/(b+c) + (b)/(c+a) + (c)/(a +b) is _____

If a, b, c are three natural numbres in A.P. such that a+b+c =21, then possible number of odered triplet (a, b, c), is

One possible condition for the three points (a,b), (b,a) and (a^(2),-b^(2)) to be collinear is

If a, b, and c are integers, then number of matrices A=[(a,b,c),(b,c,a),(c,a,b)] which are possible such that A A^(T)=I is _______.

If a ge b gt 1 , then find the largest possible value of the expression log_(a)(a//b)+log_(a)(b//a) .
