Wolfram gets it wrong?

Posted 9 years ago

Upon trying to simplify this expression ..

(38/((x)(x/5)(0.0047625)))/(0.0238125)

Worlfram gets the "Input interpretation" right... enter image description here

but its result or "alternative form" is .. enter image description here

Which is wrong, it should be (950/X²) or am i missing something?

Well, it makes sense now, thank you very much.

I think you would get the result 950/X² from the input 38/(((x) (x/5) (0.0047625))/(0.0238125)). The division is not associative: (a/b)/c is not the same as a/(b/c), even if the two-dimensional fraction notation obscures this fact with fraction lines of the same length and thickness.
