Given `A=|[a,b,2c],[d,e,2f],[l,m,2n]|,B=|[f,2d,e],[2n,4l,2m],[c,2a,b]|` , then the value of `B//A` is ___________.

If A=|{:(a,d,l),(b,e,m),(c,f,n):}|" and B = "|{:(l,m,n),(a,b,c),(d,e,f):}| , then

If x^(2a)y^(3b)=e^(5m), x^(3c)y^(4d)=e^(2n), Delta_(1)=|(5m, 3b),(2n, 4d)|, Delta_(2)=|(2a, 5m),(3c, 2n)| and Delta_(3)=|(2a, 3b),(3c, 4d)| , then the values of x and y are

Let |(a,l,m),(l,b,n),(m,n,c)||(bc-n^2,mn-lc,ln-bm),(mn-lc,ac-m^2,ml-an),(ln-bm,lm-an,ab-l^2)|=64. If the value of |(2a+3l,3l+5m,5m+4a),(2l+3b,3b+5n,5n+4l),(2m+3n,3n+5c,5c+4m)|=lambda then [lambda/2] equals

Let A={a, b, d, e}=B={c, d, f, m}, C={a, l, m, o} . Then C nn(Auu B) will be given by

If a ,b ,c ,d ,e ,f are A.M.s between 2 and 12, then find the sum a+b+c+d+e+fdot

Let D_1=|a b a+b c d c+d a b a-b|a n dD_2=|a c a+c b d b+d a c a+b+c| then the value of |(D_1)/(D_2)|,w h e r eb!=0a n da d!=b c , is _____.

If a,b,c are in H.P , b,c,d are in G.P and c,d,e are in A.P. , then the value of e is (a) (ab^(2))/((2a-b)^(2)) (b) (a^(2)b)/((2a-b)^(2)) (c) (a^(2)b^(2))/((2a-b)^(2)) (d) None of these

Consider two sets A = {a, b}, B = {e, f}. If maximum numbers of relations from A to B, A to A, B to B are l, m, n respectively then the value of 2l - m - n is

If real numbers a, b, c, d, e satisfy a+1=b + 2 = c+ 3 = d + 4 = e + 5 = a + b + c + d + e + 3 then find the value of a^2 + b^2 + c^2 + d^2 + e^2

If a,b,c,d,e, f are A. M's between 2 and 12 , then find a + b + c +d + e +f.
