## Sandiego19 Group Title find the geometric mean of the pair 196 and 4 2 years ago 2 years ago

1. shivam_bhalla

geometric mean of two numbers a and b is given by $b^2= ac$ where b-->geometric mean

2. Sandiego19

?

3. shivam_bhalla

therefore $b = \sqrt{ac}$

4. Sandiego19

5. Sandiego19

i thought it was 28

6. shivam_bhalla

well,it is 28. You have to read first what I wrote before asking such questions

7. shivam_bhalla

@Sandiego19 , don't bother about the answer. Example sum. Find the geometric mean between 16 and 64 As I stated above . a= 16 , c=64 $b =\sqrt{ac} = \sqrt{16*64} =4*8=32$ Now try your problem

8. Sandiego19

196 and 4 14x2 = 28

9. shivam_bhalla

yes @Sandiego19
