How would you go about proving:

Curl(f(r)R) where R is the position vector x^(2)i +y^(2)j +z^(2)k

I know it should equal zero but once Ihave it in its components I am struggling to make them equal zero.

Thank you

so basically the curl is evaluates to which is clearly

Trianagt, to use jakncokes' answer you will also need to know that
