Answer 2

`\huge\boxed{\bf\:2r^(7)}`

Explanation:

Let the variable be taken as 'r'.

Then, by raising it to the 7th power, we'll get the result as
`\downarrow`

`\sf\:Raise \: r \: to \: the \: 7^(th) \: power = r \: with \: 7 \: as \: its \: exponent.\\\\\sf\:Then,\\\dashrightarrow \underline{\bf\:r \: ^(7)}`

Now, by doubling the result....

`\sf\:To \: double \: the \: result = multiply \: the \: result \: by \: 2.\\\\\sf\:Then,\\\dashrightarrow \sf\:r \: ^(7) \\=\boxed{\bf\: 2r\:^(7)}`

`\rule{150pt}{2pt}`
