If the arithmetic mean between `a` and `b` is twice as great as the geometric mean, show that `a/b=(2+sqrt(3))/(2-sqrt(3))`.

If the arithmetic mean between a and b equals n times their geometric mean, then find the ratio a : b.

Insert 3 arithmetic means between 2 and 10.

Find the geometric mean between 2a and 8a^3

The arithmetic mean between a and b is twice the geometric mean between a and b. Prove that : (a)/(b) = 7+ 4sqrt3 or 7- 4sqrt3

Insert 2 geometric means between 3 and 24

If the arithmetic mean of two positive number a and b (a gtb ) is twice their geometric mean then a : b is

The arithmetic mean between two numbers is A and the geometric mean is G.Then these numbers are:
