Question

what is the mean proportional of 4 and 25​

Answer 1

Step-by-step explanation:

Mean Proportional:

If b is a mean Proportional

between a and c then

b² = ac

_________________________

Here ,

a=4 and c = 25

Let b be the mean Proportional between 4 and 25

=> b² = 4 × 25

=> b² = 100

=> b = √100

=> b = 10

Hence , the mean Proportional

of 4 and 25 is 10
