Bionials

Answer 1

\[(9+\sqrt{3})(4-3\sqrt{3)}\]

Answer 2

@Shadow i use foil here right?

Answer 3

\[28+4\sqrt{3}-27\sqrt{3}-3\sqrt{9}\]

Answer 4

That would make sense

Answer 5

\[28-23\sqrt{3}-9\]

Answer 6

\[19-23\sqrt{3}\]

Answer 7

\[(9 + \sqrt 3)(4 - 3\sqrt3)\]
\[9 \times 4 = 36\]
\[9 \times -3 \sqrt 3 = -27 \sqrt 3\]
\[\sqrt 3 \times 4 = 4 \sqrt 3\]
\[\sqrt 3 \times -3 \sqrt 3 = -3 \times 3 = -9\]
\[36 - 27 \sqrt 3 + 4 \sqrt3 - 9\]
\[27 - 23 \sqrt 3\]

Answer 8
