This is an easy question that I would like to get help with. How do you simplify this expression fully? $$\frac{1}{10x}(16-2(-5x+8)^{\frac{1}{2}})$$
Is it possible to go further?
EDIT:
The simplification is from the following question: Write the expression below so that the denominator does not contain any root expressions and simplify as far as possible:
$$-\frac{8}{5}<x<\frac{8}{5}, \quad \frac{\sqrt{8+5x}-\sqrt{8-5x}}{\sqrt{5x+8}+\sqrt{-5x+8}}=\frac{A}{B}$$
Thank you for your help!
