Which of the following choices is the geometric mean of 11 and 4?

Hey there!

Geometric mean=X1*X2*X3*Xn^1/n

Where x1,x2,x3...etc are all the numbers you have to work with and n is the number of total numbers being considered.

so we have here first let’s get the 1/n exponent out if the way;

1/n=1/2 since n=2 numbers used total, and we were given two numbers, 11 and 4. So that’s that part. Easy enough right? Great!! Now we have

(4*11)^1/2 =sqrt(44) = 2*sqrt(11)

So the answer is the next to Last or second choice.

Hope this helps you out and understand how to solve any geometric mean problem. Any questions please ask
