Question

y= √ x (x+1) derivatives

Answer 1

Use the chain rule\[\frac{d}{dx} \sqrt{x(x+1)}=\frac{2x+1}{2 \sqrt{x(x+1)}}\]

Answer 2

1 +1/2x^1/2 would be answer right

Answer 3

If this is your function:
\[\sqrt{x(x+1)}\]

the derivative is \[\frac{2x+1}{2 \sqrt{x(x+1)}}\]
Which is your answer

Answer 4

okay thanks
