Answer 1

Answer:

Let the Mean proportional bex

3:x::x:27

3/x=x/27

x^2=27*3

x^2=81

x=√81

x=9 answer

Have a good day.

Answer 2

Given that,

The digits are 3 and 27.

We know that,

The mean proportional between the digits is equal to the square of the products of given digits.

We need to calculate the mean proportional between given digits

Using given data

$mean\ proportional=\sqrt{3\times27}$

$mean\ proportional=\sqrt{81}$

$mean\ proportional = 9$

Hence, the mean proportional between 3 and 27 is 9.
