Question

What does (1/2x^-1/2)-x^1/2 simplify to?

Answer 1

anyone?

Answer 2

Is it:
\[\left( \frac{ 1 }{ 2x^{-1/2} } \right)-x^{1/2}\]
Or:
\[\left( \frac{ 1 }{ 2 }x^{-1/2} \right)-x^{1/2}\]

Answer 3

In any case, apply these rules:
\[a^{-b} = \frac{ 1 }{ a^b }\]
\[x^{1/2} = \sqrt{x}\]

Answer 4

\[\frac{1}{2 \sqrt{x}}-\sqrt{x}=\frac{1-2 x}{2 \sqrt{x}} \]
