Question

find the mean protortional between 3 and 27​

Answer 1

Given,

$3$ and $27$

We have to find the mean proportional between $3$ and $27$

As we know that the formula of mean proportional

Mean proportional $= \sqrt{ab}$

Here, $a=3$, $b=27$

Substitute the given values in the above formula,

We get

$= \sqrt{3\times27}$

$= \sqrt{81}$

$= \sqrt{9\times9}$

$= 9$

Mean proportion $= 9$

Therefor, the mean proportional between $3$ and $27$ is $9$.

Answer 2

As per the data given in the question,

We have to determine the mean proportion of the number 3 and 27.

From the question,

It is given that,

Numbers as -  3 and 27

As we know that the formula of mean proportional

Mean proportional $= \sqrt{ab}$

Here, a=3, b=27

Substitute the given values in the above formula,

Hence, we will get the mean proportion as,

$= \sqrt{3\times27}\\= \sqrt{81}\\= \sqrt{9\times9}\\= 9$

Therefore, the mean proportional between 3 and 27 will be 9.
