comment Does Temporal Logic have undecidable propositions?
According to Enya, only time can say that hardly decidable propositions are true of false. So, perhaps you're on the right track.

comment Can someone show me HOW to do this, I don't just want the answer
@user261310 What do you mean with "show"? The equation is solved for $n$ with applications of the field axioms. But I'm not sure if what you want is a deep explanation.

comment Why can't I use this shortcut here?
@Richard If you have $16x^2 = 64$ and in the next step you have $16^4$ in the right side, then you've exponentiated both sides to $4$. That is: $$[16x^2]^4 = [64]^4$$ Then it should be: $$16^4x^8 = 64^4$$

comment Simple Derivative plus tricky algebraic expression to simplify?
Wait, what do you mean with expression in the brackets? Shouldn't you take $f'(x)=0$ to find the maxima? That is, $\frac{e^{-\lambda \tau } \left(\lambda ^2 \tau ^2+\lambda \tau -e^{\lambda \tau }+1\right)}{\lambda ^2 \tau }=0$?

Why only the expression in the brackets remain?

I've compared both functions, and it seems okay. Here.

comment Simple Derivative plus tricky algebraic expression to simplify?
Differentiating it with Mathematica yields (taking it as a function of $\lambda$): $$\frac{e^{-\lambda \tau } \left(\lambda ^2 \tau ^2+\lambda \tau -e^{\lambda \tau }+1\right)}{\lambda ^2 \tau }$$

comment What is switching rows useful for?
Can you point me to some example in which this computation yields problems? It's not needed to type it if you don't want, referencing some book or article would be good.

@MauroALLEGRANZA You can use $\uparrow, \rightarrow, \downarrow, \leftarrow, \triangle, \times ,\bigcirc, \times, \square, \triangle$ to attack with Akuma's combo on Street Fighter $V$.
