Question

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

Answer 1

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!!! Thank you so much!!
