Question

Using the chain rule... how can i differentiate this?

y=xã(x-2)

Answer 1

I do not know what a with an umlaut over it means.

Answer 2

If I recall, this means √ (the dager of copy/paste from word processor screens)

If that is so, then

y = x√(x-1)

using the product rule, if

y = uv
y' = u'v + uv'
y' = (3x-2)/(2√(x-1))
