यदि a, b, c, G. P. में है तो `a^(2),ab,ac` G. P. में होंगे

If a, b, c are in G.P. then show that b^(2 ) = a.c.

If a, b, c are in G.P., show that a^(2) + b^(2), ab + bc and b^(2) + c^(2) are also in G.P.

If a, b, c are in G. P. , prove that a^2+ b^2, ab + bc, b^2 +c^2 are also in G.P

In a triangle ABC , AD is perpendicular to BC from A, if angle BAC = 90^@ , then AB^2:AC^2 is equal to : त्रिभुज ABC में, AD, A से BC पर डाला गया लम्ब है | यदि angle BAC = 90^@ है, तो AB^2:AC^2 का मान क्या होगा ?

If a+b-c = 12 and a^2+b^2+c^2=110 , then which among the following relations is true ? यदि a+b-c = 12 और a^2+b^2+c^2=110 है, तो निम्न में से कौन सा संबंध सही है ? (p) ab+bc+ca = 3 (q)ab+bc-ca = 17 (r) ab-bc+ca = 17 (s) ab-bc-ca = 17

If a, b, c are in G.P. that the following are also in G.P. sqrt(a),sqrt(b),sqrt(c ) are in G.P
