Question

calculati: 2√1440 - 4√2 x ( √180 - 3√8) urgentttttttttttt

Answer 1

$2 \sqrt{1440} - 4 \sqrt{2} \times ( \sqrt{180} - 3 \sqrt{8} )$

$= 2 \times 12 \sqrt{10} - 4 \sqrt{2} \times (6 \sqrt{5} - 3 \times 2 \sqrt{2} )$

$= 24 \sqrt{10} - 4 \sqrt{2} \times (6 \sqrt{5} - 6 \sqrt{2} )$

$= 24 \sqrt{10} - 24 \sqrt{10} + 24 \sqrt{4}$

$= 24 \times 2$

$= 48$
