Is 18 the geometric mean of 4 and 9?
No. Geometric mean of n numbers is the nth root of the product of the n numbers. → geometric mean of 4 and 9 is √(4×9) = √36 = 6.
What is the geometric mean of 4 and 18?
Remember that the geometric mean is the he nth root of the product of n numbers. Since you have two numbers it will be the square root of their product. In this case that is square root of ( 4x18)=square root of (72) which is about 8.485
What is the geometric mean of 2 and 36?
Geometric mean of 36 and 2 is 8.48528137423857 Look at link: "Calculation of the geometric mean of two numbers".
How do you find 4 consecutive numbers that have the product of 83156160?
The four numbers are 94, 95, 96, 97. The geometric mean of four consecutive (whole) numbers is going to be in the middle of the four (quite close to their arithmetic mean which is half way between the middle two numbers). The geometric mean of n numbers is the nth root of the numbers multiplied together. Here there are 4 (consecutive whole) numbers multiplied together to give 83156160, so the geometric mean of them will be the 4th root of 83156160 which will be in the middle of them. 4√83156160 ≈ 95.5 So the 4 numbers are 94, 95, 96, 97.
How do you find a geometric mean?
If there are only k numbers x(1),x(2)....,x(k), the geometric mean is the kth root of the product of these k numbers. Example: find the geometric mean of 4,3,7,8 We want the fourth root of 4 x 3 x 7 x 8 = 672 =(672)^(1/4) = 5.09146 is the geometric mean. The geometric mean is normally defined only for a set of positive numbers.
