Answer 1

3. Akar 12 = akar 4.3 =2akar 3 Akar 27=akar 9.3=3 akar 3 Akar 75=akar 25.3=5akar 3 Jadi 2+3+5 akar 3+3+3 = 10 akar 9 =10.3=30

Answer 2

1. √100 + √180 - √720 = 10 + √36.√5 - √144.√5 = 10 + 6√5 - 12√5 = 10 - 6√5.............. nomor 2) 2√150 - 3√54 - √294 + 3√496 = 2.√25√6 - 3.√9√6 - √49√6 + 3√16√31 = 2.5√6 - 3.3√6 - 7√6 + 3.4√31 = 10√6 - 9√6 - 7√6 + 12√31 = 12√31 - 6√6................ nomor 3) √12 + √27 + √75 = √4√3 + √9√3 + √25√3 = 2√3 + 3√3 + 5√3 = 10√3
