Question

find the geometric mean of the pair 196 and 4

Answer 1

geometric mean of two numbers a and b is given by
\[b^2= ac\]

where b-->geometric mean

Answer 2

?

Answer 3

therefore \[b = \sqrt{ac}\]

Answer 4

thats the answer?

Answer 5

i thought it was 28

Answer 6

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

Answer 7

@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

Answer 8

196 and 4
14x2 = 28

Answer 9

yes @Sandiego19
