ok one more thing
i have no clue what this question is asking but its asking, what's the geometric mean of 3 and 15

Answer 8

From Wikipedia.org: the geometric mean of two numbers, say 2 and 8, is just the square root of their product; that is √2 × 8 = 4.
So the geometric mean of 3 and 15 is √(3 × 15) = √45 = 3√5
