Geometric Mean. The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. First we multiply them: 2 Ã 18 = 36. Then (as there are two numbers) take the square root: â36 = 6.
What does similar mean in math? A: Similar is a term used in math when discussing geometric figures or shapes, and it means that both figures' corresponding sides are proportional, but the figures themselves are two different sizes. So one is basically a larger version of the other.
