comment Why does this equation have different number of answers?
@PeterTamaroff Yes, now I see the problem! Thanks! I'm used to the fact that you can do anything to the x-es because you don't know what their value is.

Yes, you have done only thigs that are considered "legal", and you end up with an equation that is not equal to the one you started with, and you get an answer 0 that is not allowed in the first equation. So, are you saying that you cannot necessarily multiply the whole equation and get a new equation that is equal to the first one?

@GerryMyerson Could you please clarify a little bit?

@PeterTamaroff Ok, but how can they not be the same if I haven't done anything illegal? If they aren't the same, one can't put an equal sign between all the steps...

Why you would want to evaluate this in geogebra is beyond me: It was because I wanted to draw this as a graph. But it said undefined with values of 1 or less on the x-axis. (0.5 = x)

I know that there is a difference between (−0.5)^e and −0.5^e, none of them worked. So you are saying that they cannot solve it because of their scripts, not because the math is not supposed to work?

Yes, you are correct. Thank you! So simplify the parentheses if they cannot be reduced.

comment Why does $\binom{10}{7} = \frac{10!}{(10-7)!7!}$
@Artin That was helpful. :)
