If `G_1, G_2, ..., G_n` are `n` numbers inserted between `a,b` of `G.P` then `G_1.G_2.G_3....G_n=`

If m is the A.M. of two distinct real number l and n(l , n gt 1) and G_1 , G_2 and G_3 are three geometric means between l and n , then G_1^4 + 2G_2^4 + G_3^4 equals.

if m is the AM of two distinct real number l and n and G_1,G_2 and G_3 are three geometric means between l and n , then (G_1^4 + G_2^4 +G_3^4 ) equals to

If m is the A.M. of two distinct real number l and n (l, n gt 1) and G_(1), G_(2) and G_(3) are three geometrc means between l and n then G_(1)^(4)+2G_(2)^(4)+G_(3)^(4) equals.

If m is the A.M. of two distinct real numbers l and n""(""l ,""n"">""1) and G_1, G_2 and G_3 are three geometric means between l and n, then G_1^4+2G_2^4+G_3^4 equals, (1) 4l^2 mn (2) 4l^m^2 mn (3) 4l m n^2 (4) 4l^2m^2n^2

If a be one A.M and G_1 and G_2 be then geometric means between b and c then G_1^3+G_2^3=

If a be one A.M and G_1 and G_2 be then geometric means between b and c then G_1^3+G_2^3=

If m is the A.M.of two distinct real numbers l and n(l,n>1) and G_(1),G_(2) and G_(3) are three geometric means between I and n then G_(1)^(4)+2G_(2)^(4)+G_(3)^(4) equals-

if m is the AM of two distinct real number l and n and G_(1),G_(2) and G_(3) are three geometric means between l and n, then (G_(1)^(4)+G_(2)^(4)+G_(3)^(4)) equals to

IF g_1,g_2g_3 are three geometric means between "m" and "n". Then g_1.g_3=g_2^2 =…….

If m is the A.M. of two distinct real numbers l and n ( l , n gt 1) and G_(1) , G_(2) and G_(3) are three geometric means between l and n , then G_(1)^(4) + 2 G_(2)^(4) + G_(3)^(4) equals :
