Answer 2

The geometric mean of 1 , 3 , 9 , 3 is 3

Given :

The numbers 1 , 3 , 9 , 3

To find :

The geometric mean of 1 , 3 , 9 , 3

Solution :

Step 1 of 2 :

Write down the given numbers

The given numbers are 1 , 3 , 9 , 3

Step 2 of 2 :

Find geometric mean

Number of terms = 4

Hence the required geometric mean

$\sf = \sqrt[4]{1 \times 3 \times 9 \times 3}$

$\sf = \sqrt[4]{81}$

$\sf = \sqrt[4]{ {3}^{4} }$

$\sf = 3$
