How to Calculate the Geometric Mean
Plug your numbers into the equation below., Solve for x.
Step-by-Step Guide
-
Step 1: Plug your numbers into the equation below.
If your numbers are 10 and 15, for example, plug in 10 and 15 as shown in the picture. , Start by cross-multiplying, which means multiplying the pairs of numbers diagonal to one another and then setting the results on opposite sides of an = sign.
Since x*x is x2, your equation should look like: x2 = (product of your other numbers).
To solve for x, find the square root of your product.
If you’re lucky, the results will be a whole number.
If not, you can provide a decimal answer or leave your answer in square root form, depending on what your instructor prefers.
The example here is in simplified square root form. -
