Question

simplify 12√18+6√20-3√50+8√45

Answer 1

$= > 12 \sqrt{18} + 6 \sqrt{20} - 3 \sqrt{50} + 8 \sqrt{45} \\ = > 12 \times 3 \sqrt{2} + 6 \times 2 \sqrt{5} - 3 \times 5 \sqrt{2} + 8 \times 3 \sqrt{5} \\ = > 36 \sqrt{2} + 12 \sqrt{5} - 15 \sqrt{2} + 24 \sqrt{5} \\ = > 36 \sqrt{2} - 15 \sqrt{2} + 12 \sqrt{5} + 24 \sqrt{5} \\ = > 21 \sqrt{2} + 36 \sqrt{5} \\ = > 3(7 \sqrt{2} + 12 \sqrt{5} ) \\ = > 7 \sqrt{2} + 12 \sqrt{5} \: \: \: \: \: is \: the \: \: answer$
