Giving you the answer straightaway on hgere is frownned upon so I'll just help you work through it. Start with the easy bit 5(10x+8) and times it out

I'd argue that is the simplified form.

Well

10(5x+4)(2x+2)^3
5(10x+8)(2x+2)3=5(2(5x+4))(23(x+1)3)=...5(10x+8)(2x+2)^{3}=5(2(5x+4))(2^{3}(x+1)^{3})=...
Yeah that too

I originally just took the 2 out and forgot to cube it
