Question

Plss help me in this

Answer 1

`3+√(3)` ,
`5√(5)`,
`2√(2)`, and
`18 -2√(2)`

Explanation:

1)

`√(3)(√(3)+1)`

Distribute the square root:

`√(9)+√(3)`

`3+√(3)`

2)

`(√(5) )(√(5) )(√(5) )`

`√((5)(5)(5))`

`√((25)(5))`

`(√(25)) (√(5))`

`5√(5)`

3)

`(√(2) )(√(2) )(√(2) )`

`√((2)(2)(2))`

`√((4)(2))`

`(√(4)) (√(2))`

`2√(2)`

4)

`(3√(2))^(2) -2√(2)`

`(9)(2) -2√(2)`

`18 -2√(2)`

If you need it factored:

`2(9-√(2))`

Keep in mind that square roots can be positive or negative.
