Well, first 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.
So, the first step in solving this problem is taking 2 and 3 and multiplying them
(2x3=6).
Now, for the second step, we will cube it. Since there are 2 numbers, we are going to use the 2nd root ( 2√6)
This will give us: 4.89897948557 or 5 if you would round it. This would be the Geometric Mean.
