Superfluous step in W|A step-by-step of implicit differentiation

Hello. Invoking:

derivative of x^x

and clicking on step-by-step, right near the end there is a superfluous step of “Solving for y’(x) …” where y(x) is incorrectly multiplied on the right hand side only.
Anyone notice this?
Any workaround?
Thanx.

Vaguely, it is the kind of error I would expect of AI, not of W|A. However, the Notebook Assistant gives a correct derivation.

Thanx. As I do not (yet) have the Notebook Assistant, would you please show the output you got?

Here is what I got the second time I tried (the first one was shorter):

To find the derivative of x^x, we can use logarithmic differentiation. Here are the steps:

1. Rewrite the expression using logarithms:

   Start by taking the natural logarithm of both sides of the equation y==x^x:

   ln(y)==ln(x^x)==xln(x)
2. **Differentiate both sides with respect to x:**

   Using implicit differentiation, differentiate both sides:

   d/(d x) [ln(y)]==d/(d x) [xln(x)]
   The left side differentiates to:

   1/y (d y)/(d x)
   The right side, using the product rule, differentiates to:

   ln(x)+x\[CenterDot]1/x==ln(x)+1
3. **Solve for (d y)/(d x):**

   Multiply both sides by y to solve for the derivative:

   (d y)/(d x)==y(ln(x)+1)
4. **Substitute back y==x^x:**

   Finally, replace y with x^x to get the derivative in terms of x:

   (d y)/(d x)==x^x (ln(x)+1)
So, the derivative of x^x is: 
x^x(ln(x)+1)
This matches the result you have in your notebook. If you need any more help, feel free to ask!

This produces the misstep you describe and a wrong answer in Mathematica:

WolframAlpha["derivative of x^x", {{"Input", 2}, "Content"}, 
 PodStates -> {"Input__Step-by-step solution"}]

(*  y^\[Prime](x)==x^x (1+log(x)) y(x)  *)

Yes, this is exactly how I invoked the Wolfram|Alpha step-by-step solution.

Thank you.

Interesting how Wolfram|Alpha gets it wrong, and the Assistant gets it right. Hmm.
