Find the first derivative of the function square root of x+1/4sin(2x)squared

I'm thinking you want something that looks like this
or it could be like this


use chain rule
dy/dx f(g(x))=f'(g(x))g'(x)
and √x=x^(1/2)
so
I'll do the first one first
=
=
=


the 2nd one is a bit simpler
=
=
=
=


in conclusion
= and
=
depends which one it was
