Question

I need some help on indices please.

Answer 1

\[\frac{ 1 }{ \sqrt{x-1} } +\sqrt{x-1}\]

Answer 2

well you can rewrite

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

so

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

then you will have 2 fractions with the same denominator and be able to add them

Answer 3

thanks man ^^
