(A) Yes

\newline

(B) No

Check for Separation of Variables: To determine if the differential equation can be solved using separation of variables, we need to see if we can express the equation in the form of $g(y)\,dy = h(x)\,dx$ , where $g(y)$ is a function of $y$ only and $h(x)$ is a function of $x$ only.
Rearrange the Equation: The given differential equation is $(\frac{dy}{dx} = e^{x+y})$ . To separate the variables, we need to move all the $y$ terms to one side and all the $x$ terms to the other side.
Multiply by Inverses: We can rewrite the equation as $e^{-y}\,dy = e^{-x}\,dx$ . This is done by multiplying both sides by $e^{-y}$ and $e^{-x}$ , which are the multiplicative inverses of $e^{y}$ and $e^{x}$ , respectively.
Express in Separated Form: Now we have the equation in the form $g(y)\,dy = h(x)\,dx$ , where $g(y) = e^{-y}$ and $h(x) = e^{-x}$ . This means that the differential equation can be solved using separation of variables.
