How to enter that equation?

Hello everyone,
I need help to make blocks of that equation

That's what I do, but fault results

You are not using log10…see here for the procedure required

some blocks that produce a result of 7.11937 (is that correct ?)

(I made extensive use of “external inputs” on the formulas (right click on the maths blocks)

Thank you so much, it’s now working well
