Question

20 √6 * (3√2 -2√3 )+ 5√8 * (6√3 -7√2)​

Answer 1

Explicație pas cu pas:

$20 \sqrt{6} (3 \sqrt{2} - 2 \sqrt{3} ) + 5 \sqrt{8} (6 \sqrt{3} - 7 \sqrt{2} ) \\ 20 \sqrt{6} (3 \sqrt{2} - 2 \sqrt{3}) + 5 \times 2 \sqrt{2} (6 \sqrt{3} - 7 \sqrt{2} ) \\ 20 \sqrt{6} (3 \sqrt{2}- 2 \sqrt{3} ) + 10 \sqrt{2} (6 \sqrt{3} - 7 \sqrt{2} ) \\ 10 \sqrt{2} (2 \sqrt{3} (3 \sqrt{2} - 2 \sqrt{3} ) + 6 \sqrt{3} - 7 \sqrt{2} ) \\ 10 \sqrt{2} (6 \sqrt{6} - 12 +6 \sqrt{3} - 7 \sqrt{2} )$

1. scoate factorii de sub radical

2. inmulteste numerele

3. scoate-l factor comun pe 10radical din 2

4. scapa de paranteze
