Question

calculați vă rog!!!urgent ​

Answer 1

Răspuns:

$\sqrt{6} ( \sqrt{24 } - \sqrt{6} ) = \\ \sqrt{6} (2 \sqrt{6} - \sqrt{6} ) = \\ \sqrt{6} \sqrt{6} = 6$

$(2 - \frac{ \sqrt{3} }{4} )(2 + \frac{ \sqrt{3} }{4} ) = \\ 4 - \frac{3}{16 } = \frac{64 - 3}{16} = \frac{61}{16}$

la al 2 lea punct am amplificat (4-3/16)
