Answer 1

Answer:

let the mean proportional between 18 and 2 is x

so,

18 : x= x : 2

=> 18/x=x/2

=> x^2=36

=> x=√36=6

mean proportional is 6

Answer 2

Answer:

If we have to find the mean proportional , first we have to multiply the 2 given numbers , then we have to find the square root out of their product .

Step-by-step explanation:

solution

18 × 2 = 36

square root of 36 = 6
