ABCD is a square of length a, a in N , a > 1. Let L_1, L_2 , L_3... be points on BC such that BL_1 = L_1 L_2 = L_2 L_3 = .... 1 and M_1,M_2 , M_3,.... be points on CD such that CM_1 = M_1M_2= M_2 M_3=... = 1 . Then sum_(n = 1)^(a-1) ((AL_n)^2 + (L_n M_n)^2) is equal to :

Consider the lines L_(1) : x/3 +y/4 = 1 , L_(2) : x/4 +y/3 =1, L_(3) : x/3 +y/4 = 2 and L_(4) : x/4 + y/3 = 2 .Find the relation between these lines.

Two rays emanate from the point A and form an angle of 43 with one another. Lines L_1, L_2, and L _3, (no two of which are parallel) each form an isosceles triangle with the original rays. The largest rigle of the triangle formed by lines L_1, L_2, and L_3, is -

Dimension of sqrt((in_(0))/(mu_(0))) are (A) [M L^(2) T^(-3) A^(-2)] (B) [M^(-1) L^(-2) T^(3) A^(2)] (C) [M^(2)L^(2)T^(-3) A^(2)] (D) [M^(-1) L^(2) T^(3) A^(2)]

If coefficient of a^2 b^3 c^4 in(a+b+c)^m (where n in N ) is L(L != 0), then in same expansion coefficient of a^4b^4c^1 will be (A) L (B) L/3 (C) (mL)/4 (D) L/2
