Answer 2

Explanation:

Curl means cross product with del operator.

$b.curl(a) - a.curl(b) \\ = 0 - 0 \\ = 0$

E.g

$\left[\begin{array}{ccc}i&j&k\\ \frac{∂}{∂x} &\frac{∂}{∂y} &\frac{∂}{∂z} \\ax&ay&az\end{array}\right] \\ \\ i(0 - 0) + j(0 - 0) + k(0 - 0) \\ \\ = 0</p><p></p><p>$

as other be zero
