Yes, it would be counted twice. All root possibilities for any given polynomial would be a unique combination, and there is no rule saying that number can't repeat or anything either. Thanks, I'm going to think about this and see what I come up with.

Not necessarily, more so the permutations where all coefficients, the x variable, and constant term are considered and all some combination between -100 and 100 such that, the combination satisfies the RS to equal 0. I'm trying to imagine a 6D surface: ax³ + bx² + cx + d = y ... It would...

Sorry if this is the wrong thread, seems appropriate but I'm kind of just learning math. This started as a thought experiment to learn some new technique. I've been trying to compute the total number of integer polynomials under certain restrictions: such that all coefficients, x, and the...

:smile:I forgot to square the Planck constant and wavelength when working with the units alone... Were all good, thanks for the tip, I thought it might be easier to think about working with the units without numbers but I forgot about the powers of the value to begin.. I certainly see the...

I'm not sure if you can see where I'm going wrong in my units, I've tried using Plancks constant with J/s too but its also not Volts, although I know it is, but where am I going wrong.

I might be doing something wrong here, I tried this a couple of ways but I don't exactly line up with \frac{kg⋅m^2}{A⋅s^3} I end up with this \frac{m}{A⋅s^2}

Thank you for the critical thinking exercise.

But why the heck does the equation render a value within the realm of the centi-volt? I pull 15078.5 from the equation but I'm not sure the units, and if you say its 150 volts, I'm in a new place of confusion.

BvU, you're honestly a tank. Thanks dude.

I need to learn to read still...

...and wait, isn't electric potential diff in eV.. I jump at the conclusion due to the ΔV symbol and as eV's seem to be standard in this study? ... Thanks for pointing that out.

Question about significant digits... Is this one significant digit because the question is 1.0⋅10-10m?

It's meters, and thanks for your help I mostly needed to make sure it was right before I put in the numbers; that's the easy part :p.

I was looking at this and my second algebra is terrible... I meant to write this but I was awake for way too long.Since λ= \frac{h}{\sqrt{2⋅m⋅E}} → E= \frac{h^2}{2⋅m⋅λ^2} ΔV = \frac{E}{e} = \frac{(\frac{h^2}{2⋅m⋅λ^2})}{e} = \frac{h^2}{2⋅m⋅e⋅λ^2}
