Question

2. Calculând 3(3√2-2√3)-4(2√2-√3), rezultatul obținut este:​

Answer 1

Răspuns:

$3(3 \sqrt{2} - 2 \sqrt{3} ) - 4(2 \sqrt{2} - \sqrt{3} ) \\ 9 \sqrt{2} - 6 \sqrt{3 } - 8 \sqrt{2} - 4\sqrt{3} \\ \sqrt{2} - 2\sqrt{3}$

Answer 2

Rezolvare:

$3(3\sqrt{2} - 2\sqrt{3} ) - 4(2\sqrt{2} - \sqrt{3})$
=$9\sqrt{2} -6\sqrt{3} -8\sqrt{2} +4\sqrt{3}$
=$\sqrt{2} - 2\sqrt{3}$
