Answer 1

а)

$2 \sqrt{3} = \sqrt{3 \times 2^{2} } = \sqrt{12}$

б)

$3 \sqrt{10} = \sqrt{10 \times {3}^{2} } = \sqrt{90}$

в)

$12 \sqrt{2} = \sqrt{2 \times {12}^{2} } = \sqrt{288}$

г)

$2 \sqrt{21} = \sqrt{21 \times {2}^{2} } = \sqrt{84}$

д)

$11 \sqrt{11} = \sqrt{11 \times {11}^{2} } = \sqrt{1331}$
