Answer 1

Answer:

     =4sqrt(10)

Step-by-step explanation:

The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers

geometric mean = sqrt(8*20)

                            =sqrt(160)

                             = sqrt(16*10)

We know that sqrt(ab) = sqrt(a) sqrt(b)

                            =sqrt(16) sqrt(10)

                             =4sqrt(10)
