Question

find the GM b/w
1/3, 243​

Answer 1

Step-by-step explanation:

Given:-

Two numbers are 1/3 and 243

To find:-

Find the Geometric Mean?

Solution:-

Given numbers are 1/3 and 243

Let a=1/3 and c=243

Let the geometric mean=b

We know that a,b,c are in the GP then the geometric mean b²=ac or b=√(ac)

=>b=√(1×243/3)

=>b=√81

=>b=9

Answer:-

The geometric mean=9

Answer 2

Step-by-step explanation:

Geometric Mean = under root a multiple b

so , under root 1/3 multiple 243 =under root 81 =9

correct answer is 9
