Question

Find the mean proportional for 1/2 , 32

Answer 1

Step-by-step explanation:

how we can find the mean propotional of x+1÷x-1 and x^2-1

Answer 2

Answer:

The mean proportional for 1/2 , 32 is 4.

Step-by-step explanation:

Given two digits are $\frac{1}{2}$ and 32.

We want to find mean proportional for $\frac{1}{2}$ and 32.

Now question is what is mean proportional ?

Mean proportional of two numbers, a and b is √ab.

By some examples, we understand this concept more easily.

Example -1:

We are taking two numbers 5 and 10.

So,mean proportion of 5 and 10

$= \sqrt{5 \times 10} \\ = \sqrt{5 \times 5 \times 2} \\ = 5 \sqrt{2}$

Example -2:

We are taking two numbers 50 and 100.

So, mean proportional of 50 and 100

$= \sqrt{50 \times 100} \\ = \sqrt{50 \times 2 \times 50} \\ = 50 \sqrt{2}$

Here given two numbers are $\frac{1}{2} \: and \: 32$

Mean proportional of $\frac{1}{2} \: and \: 32$

$= \sqrt{ \frac{1}{2} \times 32 } \\ = \sqrt{16} \\ = \sqrt{4 \times 4} \\ = 4$
