यदि a,b,c,d गुणोत्तर श्रेढी में हों, तो सिद्ध कीजिए कि `:`
`(b+c)(b+d)=(c+a)(c+d)`

If a ,b,c , d are in G.P. prove that (b + c)(b + d) = (c + a)(c+d)

If (a+b)/(b+c)=(c+d)/(d+a) , then

If a,b,c,d are in GP then prove thst (b+c)(b+d) =(c+a)(c+d)

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

If a ,\ b ,\ c ,\ d are in proportion, then (a) a b=c d (b) a c=b d (c) a d=b c (d) None of these

If a ,b ,c ,d in R^+ and a ,b ,c,d are in H.P., then (a) a+d > b+c (b) a+b > c+d (c) a+c > b+d (d)none of these

If a ,b ,c ,d in R^+ and a ,b ,c,d are in H.P., then (a) a+d > b+c (b) a+b > c+d (c) a+c > b+d (d)none of these

If a ,b ,c ,d in R^+ and a ,b ,c,d are in H.P., then (a) a+d > b+c (b) a+b > c+d (c) a+c > b+d (d)none of these
