]CORRECT ANS IS (B)Answer.: As, NEWS = (16+7+25+21)^2 = 69^2 = 4761, in similar way TJWR = (22+12+25+20)^2 = 79^2 = 6241, There is option (D) which is 6241, and this option (D) is correct. The question is great. As there is no answer I am attaching bothe answer and question together.

B = 1+1 (0-1)

Then, which of the following statement is true.

a) A > B b) B < A c) A= B

Vector equation of the plane passing through points A(a) , B(b) and parallel to the vector c is [ r b c] + [ r c a] = [ a b c] ........ prove this plz....What is the value of log(infinity) ?

A) 99
