Question

Va rog frumos sa ma ajutați la acest subpunct !

Answer 1

$\frac{ \sqrt{49}}{ \sqrt{12^2+5^2} } =\ ? \\ \\ \\ \sqrt{49}=7 \\ \sqrt{12^2+5^2} = \sqrt{144+25} = \sqrt{169} = 13 \\ \\ \frac{ \sqrt{49}}{ \sqrt{12^2+5^2} } = \frac{7}{13}$

Answer 2

√49=7

√12²+5²=√144+25=√169=13

7/13=0,53846
