Question

em cada item calcule a soma dos radicais

Answer 1

$a) 3\sqrt{2} -4\sqrt{2} =-\sqrt{2}\\b) 3\sqrt[4]{5} -2\sqrt[4]{5} -\sqrt[4]{5} =0\\c) \sqrt{3} .\sqrt{4} - 3\sqrt{3} +2\sqrt{3} \sqrt{25} \\2\sqrt{3} -3\sqrt{3} +10\sqrt{3} =12\sqrt{3} +3\sqrt{3} =9\sqrt{3} \\\\2 a) \sqrt{2} .\sqrt{6} =\sqrt{2.6} =\sqrt{12}$
