no its a variable

Answer 6

yes but is EVERYTHING over X or just the power

Answer 7

everything over x

Answer 8

ok thx

as x approched 0

Answer 10

Not true^^. Multiply top and bottom by 1+(1-2x)^(1/2) giving:
\[\lim_{x \rightarrow 0}\frac{1-(1-2x)}{x(1+\sqrt{1-2x})}\]
This reduces to:
\[\lim_{x \rightarrow 0}\frac{2}{1+\sqrt{1-2x}}\]
Evaluating gives you 1.
