Answer:


10√(14) + 8√(21) + 30 √(3) +36√(2)\\\\

Explanation:


( 2 \sqrt7 + 3 \sqrt6)(5\sqrt2 + 4\sqrt3)\\\\= 2\sqrt7(5\sqrt2 + 4\sqrt3) + 3\sqrt6 ( 5\sqrt2 + 4\sqrt3)\\\\=10√(7 * 2) + 8√(7 * 3) + 15√(6 * 2) + 12√( 6* 3)\\\\=10√(14) + 8√(21) + 15 √(12) +12√(18)\\\\= 10√(14) + 8√(21) + 15 √(4 * 3 ) +12√(9 * 2)\\\\= 10√(14) + 8√(21) + 15 √(2^2 * 3) +12√(3^2 * 2)\\\\= 10√(14) + 8√(21) + 30 √(3) +36√(2)\\\\
