The correct answer is, obviously, 34/7.
Answer:
5/8
Step-by-step explanation:
Geometric mean is found by multiplying the n number of values and then taking the n-root.
To do this with these numbers, sqrt((9/16)*(25/36)) = (3/4)(5/6) = (1/4)(5/2)= 5/8
I hope this helps! :)
As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n
