GEOMETRIC MEAN (G.M.) Properties of GM The product of n geometric means between two given numbers is nth power of the single G.M. between them i.e. if a and b are two given numbers and Gi, G2,Gn are n geometric means between them, then If A and G are respectively arithmetic and geometric means between two positive numbers a and b then

If the A.M. between two number is 34 and their G.M. is 16, then the two number are a. 64 and 8 c. 8 and 4 b. 64 and 4 c. none of these.

If the A.M. between two number is 34 and their G.M. is 16, then the two number are a. 64 and 8 c. 8 and 4 b. 64 and 4 c. none of these.

If the A.M. between two number is 34 and their G.M. is 16, then the two number are a. 64 and 8 C. 8 and 4 b. 64 and 4 c. none of these. Sabing thodo 2 CA64

The A. M. between two number b and c is a and the two G.M.s between them are g, and g2. If g13gkabc, then k equal to
