Answer:

3+\sqrt{3} , 5\sqrt{5}, 2\sqrt{2}, and 18 -2\sqrt{2}

Step-by-Step Explanation:

1)

\sqrt{3}(\sqrt{3}+1)

Distribute the square root:

\sqrt{9}+\sqrt{3}

3+\sqrt{3}

2)

(\sqrt{5} )(\sqrt{5} )(\sqrt{5} )

\sqrt{(5)(5)(5)}

\sqrt{(25)(5)}

(\sqrt{25}) (\sqrt{5)}

5\sqrt{5}

3)

(\sqrt{2} )(\sqrt{2} )(\sqrt{2} )

\sqrt{(2)(2)(2)}

\sqrt{(4)(2)}

(\sqrt{4}) (\sqrt{2)}

2\sqrt{2}

4)

(3\sqrt{2})^{2} -2\sqrt{2}

(9)(2) -2\sqrt{2}

18 -2\sqrt{2}

If you need it factored:

2(9-\sqrt{2})

Keep in mind that square roots can be positive<em> or</em> negative.
