Answer:

[tex]3\sqrt{3} - 4\sqrt{2}[/tex]

Step-by-step explanation:

The expression (2 square root sign 27) - (3 square root sign 32) is [tex]2\sqrt{27} - 3\sqrt{32}[/tex].

To simplify, simplify inside the radicals by removing perfect square factors.

[tex]\sqrt{27} =\sqrt{9*3} =3\sqrt{3}[/tex]

[tex]\sqrt{32} =\sqrt{16*2} =4\sqrt{2}[/tex]

The expression becomes [tex]3\sqrt{3} - 4\sqrt{2}[/tex].

This cannot be simplified anymore because whats under the radical is not the same.
