Question

3. Find the mean proportional between (i) 3 and 27 (ii) 0.06 and 0.96.​

Answer 1

Answer:

i) 9  (ii) 0.24

Step-by-step explanation:

i) Mean proportional between 3 and 27=  

3×27 = 81 = 9

​(ii)Mean proportional between 0.06 and 0.96=

0.06*0.96=0.576 = 0.24

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:-

               $1)3 \ and\ 27.\\2)0.06\ and\ 0.96.$

              To find:- Value of the given expression.

              Solution:-

• As per the data, we have to find proportional between given numbers.
• Therefore we get,

      $1)3 \ and\ 27.$

         The mean proportional between  3 and 27 is

               $\sqrt{3 \times 27}\\=\sqrt{81}\\=9.$

         $2)0.06\ and\ 0.96.$

        The mean proportional between  0.06 and 0.96 is

             $\sqrt{0.06\times 0.96} \\=\sqrt{0.0576} \\=0.24.$
