Question

find the mean propotional of 0.081 and 0.09​

Answer 1

Answer:

Answer will be 0.027

Step-by-step explanation:

I think there is a printing mistake for 0.081...It will be 0.0081

Let the mean proportional be x

0.0081:x::x:0.09

or, 0.0081/x = x/0.09

or, x^2= 0.0081×0.09

or, x= √0.0081 ×√0.09

or, x= 0.09×0.3

or, x= 0.027
