Question

what's the geometric mean of 7 and 9.

Answer 1

To find the geometric mean of two numbers you...

step 1) multiply the two numbers

step 2) take the square root of the result in step 1

Answer 2

geometric mean between
a and b is
sqrt(ab)

Answer 3

7*9 doesn't equal 56, but you have the right idea

Answer 4

and the correct final answer

Answer 5

@jim_thompson5910 My bad.\[M=\sqrt{a*b}\]\[M=\sqrt{7*9}\]\[M=\sqrt{63}=3\sqrt{7}\]

Answer 6

geometric mean is \[b=\sqrt{ac}\]

Answer 7

Geometric mean is:\[m=\sqrt[n]{\prod\limits_{i=1}^{n}x_i}\]In this case\[x_1=7~and~x_2=9,~n=2\]
