Irrotational means curl is zero
solenoidal means divergence is zero
Take the divergence of
(∇f × G )f
and see what happens

would taking the divergance mean that
(∇f × G )f =0 and work from there??

Yes
I do not remember right now all the vector identities, but there would be curlG also appearing in the proof which of course they would be zero

∇ · (fG ) = (∇f) · G + f∇ · G
∇ · (F×G ) = (∇ × F )·G − F· (∇ × G )
Ive gone through all of my identities and picked these 2 out that can solve this. Are these 2 suitable for this question??
