Answer 1

Explicação passo-a-passo:

$a)~~\sqrt{12} =\sqrt{4} .\sqrt{3} =2\sqrt{3} \\ \\ b)~~\sqrt{18} =\sqrt{9} .\sqrt{2} =3\sqrt{2} \\ \\ c)~~\sqrt{50} =\sqrt{25} .\sqrt{2} =5\sqrt{2} \\ \\ d)~~\sqrt{8} =\sqrt{4} .\sqrt{2} =2\sqrt{2} \\ \\ e)~~\sqrt{72} =\sqrt{36} .\sqrt{2} =6\sqrt{2} \\ \\ f)~~\sqrt{75} =\sqrt{25} .\sqrt{3} =5\sqrt{3} \\ \\ g)~~\sqrt{98} =\sqrt{49} .\sqrt{2} =7\sqrt{2} \\ \\ h)~~\sqrt{99} =\sqrt{9} .\sqrt{11} =3\sqrt{11} \\ \\ i)~~\sqrt{200} =\sqrt{100} .\sqrt{2} =10\sqrt{2}$
