f is a real valued function in Rn

I need to show that Grad(f^n) = nf^(n-1)*grad(f)

I am not sure how to get the grad(f) on the right side. It looks like the chain rule but I can't seem to figure it out... anyone can help ?

I have a 2019 macbook pro with 64gb of ram and my gaming pc has been in the closet since 2018
