Question #f7644

Answer 1

`y` is a constant with respect to `x`, so the derivative of log (xy) is `y 1/x`

Explanation:

The derivative of `log x` is `1/x`, and since `y` is a constant with respect to `x`, the derivative of `xy` is `y`. Then the chain rule gives: the derivative of log (xy) is `y 1/x`
