Translated by Google: "How to express the power in the Labview formula node? Is it indicated by the two asterisks as shown in the figure?"

If you have a question, please attach a simple VI containing your formula node and typical input values. We cannot debug images! Do you get an error?

Personally, I recommend to eliminate the formula node and use plain graphical code. Much simpler! Here's the power of x function.

Are you sure your formula should not be:

fi=f1*((f2/f1)**(i/(N-1)));

instead of your:

fi=f1*((f2/f1)**(i/N-1));

[altenbach]

Here's how it would look with the above correction.

One possible alternative without formula node is shown below. Same result! (There are many ways to do that!).

Note that the same can be achieved with the ramp pattern set to logarithmic (bottom). That's what I would use!
