The geometric mean of two numbers, ( a ) and ( b ), is calculated using the formula ( \sqrt{a \times b} ). For 9 and 30, this is ( \sqrt{9 \times 30} = \sqrt{270} ). Simplifying ( \sqrt{270} ), we get ( 3\sqrt{30} ), which is approximately 16.43. Thus, the geometric mean of 9 and 30 is ( 3\sqrt{30} ) or approximately 16.43.
