Question

If x and y are two numbers having same sign
(positive or negative), their G.M. is given by
G= xy.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given two numbers as: $x, y$

Recall $G.M$ (geometric progression) is termed as the nth root of the product of n values.

That is:

$G.M = \sqrt{x\times y}$

$G.M = \sqrt{xy}$.

Therefore:

$G=G.M=\sqrt{xy}.$
