You are correct, how are we to prove you wrong when you are right -,-

You will need to define 'Impossible' 

The word 'Impossible' is very universal. Just like the word 'Happiness'. One could make another happy, but not necessarily make another happy.

Many people have different definitons of it. For example, If I were to give you a extremely hard question, it would be 'impossible' for you to solve it. But it would be 'possible' for me to. But, if you are looking at a bigger scale, things can be possible if you believe you can. :P

$${{\mathtt{32}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)} = {\mathtt{2}}$$

$${{\mathtt{32}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)}$$is also equivalent to the fith root of 32.

Not enough Infomation.

Possible Answers: $$x$$,$$infinity$$,$$zero$$

$${\mathtt{0.2}}{\mathtt{\,-\,}}{\mathtt{0.5}} = {\mathtt{\,-\,}}{\frac{{\mathtt{3}}}{{\mathtt{10}}}} = -{\mathtt{0.3}}$$

If you mean 'out' as in remove, you can always multiply the number by -1 providing it is a negative number in the first place.

$${\mathtt{\,-\,}}\left({\mathtt{5}}{\mathtt{\,\times\,}}\left(-{\mathtt{1}}\right)\right) = {\mathtt{5}}$$

If you are smart enough to ask that question. Use your brain on this:

Does the grade A++ really exist? My teacher used to give the grade S when we ace a test. S as in Superior.
