Identify the numbers for which you want to find the geometric mean. In this case, the numbers are 4 and 9.
Recall the formula for the geometric mean of two numbers \(a\) and \(b\):
\[\text{Geometric Mean} = \sqrt{a \times b}\]
Substitute the given numbers into the formula:
\[\text{Geometric Mean} = \sqrt{4 \times 9}\]
Calculate the product inside the square root:
\[4 \times 9 = 36\]
Take the square root of the product to find the geometric mean:
\[\sqrt{36}\]
