The geometric mean of 9 and 81 is 27.0
mean = (4 + 81)/2 = 85/2 = 42.5
Just use the definition of geometric mean. Multiply the two numbers, then take the square root of the result. (To take the geometric mean of three numbers, multiply all of them, then take the cubic root, etc.)

it's 49 over 81. prime numbers can't be reduced. you're welcome.

Their geometric mean is:sqrt(42*(1/9)2)=sqrt(16*(1/81))=sqrt(16/81)=4/9-------------------The geometric mean of a set of n terms is equal to the nth root of the product of those n terms. The geometric mean of 4 and 1/9 is sqrt(4*(1/9)) = sqrt(4/9) = 2/3.

81 - 49 = 32
The GCF of 49 and 81 is 1.
