Question

The geometric mean between 1/2 and 1/8 is

Answer 1

Answer:

Geometric mean is 1/4

Step-by-step explanation:

Let a be the G.M between these two no.

1/2 a 1/4

By formula

a= √xy........x and y are the no.s

a =√1/2×1/8

a = 1/4

Answer 2

The geometric mean between 1/2 and 1/8 is 1/4

Given : Two numbers 1/2 and 1/8

To find : The geometric mean

Tip :

If a and b are two given numbers then the Geometric mean between a and b is

$\sf{ = \sqrt{ab} }$

Solution :

Step 1 of 2 :

Write down the given two numbers

The given two numbers are 1/2 and 1/8

Step 2 of 2 :

Find the geometric mean

The required geometric mean

$\displaystyle \sf{ = \sqrt{ \frac{1}{2} \times \frac{1}{8} } }$

$\displaystyle \sf{ = \sqrt{ \frac{1}{16} } }$

$\displaystyle \sf{ = \frac{1}{4} }$
