Hasil 2√20 + 5√45 - √500 adalah.. Tolong bantu jawab ya,pake caranya nya

[tex] = 2 \times \sqrt{4} \times \sqrt{5} + 5 \times \sqrt{9} \times \sqrt{5} - \sqrt{25} \times \sqrt{20 } \\ = 2 \times 2 \times \sqrt{5} + 5 \times 3 \times \sqrt{5} - 5 \times 2 \times \sqrt{5} \\ = 4 \sqrt{5} + 15 \sqrt{5} - 10 \sqrt{5} \\ = 9 \sqrt{5} [/tex]
