OK, so, my first question is what are these for? If they're for a homework question or such I am slightly confused as Wolfram Alpha says there are no solutions to the first one. I'm inclined to agree. Certainly there's no way to make it much nicer.

Second one:

Wolfie. It's a bit complicated. 4th roots of 3? No thanks.

Yeah, the first one is a bit weird, since the roots of x and 1-x would imply that x is between 0 and 1 (otherwise the roots wouldn't be real numbers), which would mean those two square roots would also be between 0 and 1. I don't see how you could subtract two numbers like that to get something greater than 3/sqrt(5) (which is greater than 1).

This was kind of homework, it was a preparation for a test. Hopefully I don't get something like this in the actual test
