Question

How we find mean proportional number is 9 and6

Answer 1

Step-by-step explanation:

We have to find the mean propotional in 9 and 6.

Let the mean propotional be x.

9:x::x:6

9/x=x/6

x^2=9×6 ( by cross multiplication)

x^2=48

x=square root of 48.

hence, the mean propotional of 9&6 is square root of 48.

Hope it helps.
