Simply add the R's and ignore the squared numbers.

\[2r^2\]

Answer 4

well my answer needs to become \[x \sqrt{x}\]

\[2r^2\] is equal to \[r \sqrt{r}\]

Answer 6

We're just taking the squareroot of the number. If we plug out numbers back in, we get \[r^2\]

Answer 7

You can also say \[4r^4\sqrt{2^2}\]
