multiply (root 3 + root 2) and (2 root 5 - 7 root 3)

Answer 1

$\huge {\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

$( \sqrt{3} + \sqrt{2} ) \times (2 \sqrt{5} - 7 \sqrt{3} ) \\ \\ = \sqrt{3} \times (2 \sqrt{5} - 7 \sqrt{3} ) + \sqrt{2} \times (2 \sqrt{5} - 7 \sqrt{3} ) \\ \\ = 2 \sqrt{15} - 21 + 2 \sqrt{10} - 7 \sqrt{6} \\ \\ = 2( \sqrt{15} + \sqrt{10} ) - 7 ( \sqrt{6} + 3)$

Answer 2

Step-by-step explanation:

√3 (2 √5 + 7√3) √2 ( 2 √5 + 7 √3)

(2 √5×3 + 7×√3×√3 ) (2 √5×2 + 7√3×2)

2√15 + 7 ×3 + 2√10 + 7√6

ans (2√15 + 2√10) (7√6 + 7×3)
