Question

Answer 1

1) \(2\sqrt{3}.3.\sqrt{27}=2\sqrt{3}.3\sqrt{3}.3=54\)

2) \(-3\sqrt{32}\left(-4\sqrt{2}\right)=12\sqrt{2}.4\sqrt{2}=96\)

4) \(-2\sqrt{33}.\sqrt{3}=-2\sqrt{99}=-6\sqrt{11}\)

5) \(8\sqrt{6}.\left(-2\sqrt{24}\right)=-8\sqrt{6}.4\sqrt{6}=-192\) 

Answer 2

1: \(2\sqrt{3}\cdot3\cdot\sqrt{27}\)

\(=6\sqrt{3}\cdot3\sqrt{3}\)

=54

2: \(-3\sqrt{32}\cdot\left(-4\sqrt{2}\right)\)

\(=12\sqrt{2}\cdot4\sqrt{2}\)

=96

4: \(-2\sqrt{33}\cdot\sqrt{3}=-6\sqrt{11}\)

5: \(8\sqrt{6}\cdot\left(-2\sqrt{24}\right)\)

\(=-8\sqrt{6}\cdot4\sqrt{6}\)

=-192
