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

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

    @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
