(x^2)+2x=y? or X^(2+2x)=y either way whats the value of y? so we can determine x

It depends entirely on the value of x.
Its the square root of 2 times x Ambiguous. More clear is x times square root of 2
That expression can't be simplified. It has to written, and evaluated, just as it appears in the question: [ sqrt(x + 2) ] + [ sqrt(x + 3) ]
Yes, I think so even though it has been 50 years since I took Calculus . Note that x times the square root of x is just x to the 3/2 power, so you can do the obvious. The answer is x to the 5/2 divided by 5/2 + x
5 - x^2 = (the square root of 5 minus x)(the square root of 5 plus x)
