## anonymous 4 years ago find the geometric mean of the pair 196 and 4

1. anonymous

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

2. anonymous

?

3. anonymous

therefore $b = \sqrt{ac}$

i thought it was 28

6. anonymous

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

@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

196 and 4 14x2 = 28

yes @Sandiego19
