Can I get some help? Thanks!

See a solution process below

Explanation:

To expand the terms in the parenthesis multiply each term within the parenthesis by the term outside the parenthesis:

`color(red)(sqrt(7x))(sqrt(x) - 7sqrt(7)) =>`

`(color(red)(sqrt(7x)) * sqrt(x)) - (color(red)(sqrt(7x)) * 7sqrt(7)) =>`

`sqrt(7x * x) - 7sqrt(7x * 7) =>`

`sqrt(7x^2) - 7sqrt(49x) =>`

`sqrt(7 * x^2) - 7sqrt(49 * x) =>`

`(sqrt(7)sqrt(x^2)) - 7sqrt(49)sqrt(x) =>`

`xsqrt(7) - (7 * 7)sqrt(x) =>`

`xsqrt(7) - 49sqrt(x)`
