Answer:

  • 3\sqrt{6}\times \:2\sqrt{3}=18\sqrt{2}
  • 5\sqrt{12}+3\sqrt{3}=13\sqrt{3}

Step-by-step explanation:

                                                        1)

Given the expression

3\sqrt{6}\:\times \:2\sqrt{3}

\mathrm{Factor\:integer\:}6=3\times \:2

=3\sqrt{3\times \:2}\times \:2\sqrt{3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

=3\sqrt{3}\sqrt{2}\times \:2\sqrt{3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt{a}\sqrt{a}=a

=3\times \:2\times \:3\sqrt{2}

=18\sqrt{2}

Thus,

3\sqrt{6}\times \:2\sqrt{3}=18\sqrt{2}

                                                        2)

Given the expression

5\sqrt{12}+3\sqrt{3}

\:=\:5\sqrt{\left(4\right)\left(3\right)}+3\sqrt{3}

=\:5\times 2\sqrt{\left(3\right)}+3\sqrt{3}

=10\sqrt{3}+3\sqrt{3}

\mathrm{Add\:similar\:elements:}\:10\sqrt{3}+3\sqrt{3}=13\sqrt{3}

=13\sqrt{3}

Thus,

5\sqrt{12}+3\sqrt{3}=13\sqrt{3}
