Find y Prime & y Double Prime

Find y ' and y "

y = rt{4 − x^2}

Let rt = square root

Let me see.

I must find the first and second derivative of the square root function.

Note:

I think the best way to tackle this problem is to
rewrite the given function as a power of x.

Doing this, I get y = (4 - x^2)^(1/2).

I now can apply the chain rule.

Yes?

Considering that the original function was given as a square root, must
I write the final answer as a square root? Is that mandatory?

Thanks
