Find the geometric mean of 7 and 28

To find the geometric mean of two numbers, you need to multiply them together and then take the square root of the product.

So in this case, the product of 7 and 28 is 7 * 28 = 196.

Then, you need to take the square root of the product: √196 ≈ 14.

Therefore, the geometric mean of 7 and 28 is approximately 14.
