(2×√2+1)×(3×√2−4)va rog frumooossss!!!!!


Răspuns :

[tex](2 \times \sqrt{2} + 1) \times (3 \times \sqrt{2} - 4)[/tex]

[tex] = (2 \sqrt{2} + 1) \times (3 \sqrt{2} - 4)[/tex]

[tex] = 6 \sqrt{4} - 8 \sqrt{2} + 3 \sqrt{2} - 4[/tex]

[tex] = 6 \times 2 - 8 \sqrt{2} + 3 \sqrt{2} - 4[/tex]

[tex] = 12 - 5 \sqrt{3} - 4[/tex]

[tex] = - 5 \sqrt{3} + 8[/tex]
