Find all the second partial derivatives. v = e5xey

I'm taking the liberty of editing your function v = e5xey: It should be

v = e^5x^ey, with " ^ " indicating exponentiation.

Did you mean e^ (5x) or (e^5) x? I'll assume it's e^ (5x).

The partial of v = e^ (5x) e^y with respect to x is e^ (5x) (5) * e^y, or 25x*e^y.

The partial of v = e^ (5x) e^y with respect to y is e^ (5x) e^y.
