Question

Cine imi explica si mie cum se afla produsul si catul radicalilor???Va rog e urgent maine dau test la matematica!!!!Si nu stiu acest lucru...

Answer 1

       
$Produsul: \\ \sqrt{a} * \sqrt{b} = \sqrt{a*b} \\ Exemple: \\ \sqrt{6}* \sqrt{24}= \sqrt{6*24} = \sqrt{144}=12 \\ \sqrt{3}* \sqrt{3} = \sqrt{3*3}= \sqrt{9}=3 \\ \sqrt{3}* \sqrt{6}= \sqrt{3*6} = \sqrt{18} = \sqrt{9*2} =3 \sqrt{2} \\ \\ \\ Catul: \\ \frac{ \sqrt{a} }{ \sqrt{b}}= \sqrt{ \frac{a}{b}} \\ Exemple: \\ \frac{ \sqrt{6} }{ \sqrt{3}}= \sqrt{ \frac{6}{3}}= \sqrt{2} \\ \frac{ \sqrt{12} }{ \sqrt{3}}= \sqrt{ \frac{12}{3}}= \sqrt{4}=2$
