A.
12√6 - 7√6 + 3√6 = 5√6 + 3√6 = 8√6

b.
6√5 + √5 - 20√5 = 7√5 - 20√5 = -13√5

c.
√700 + √180 + √80 - √721
= √(100x7) + √(36x5) + √(16x5) - √721
= 10√7 + 6√5 + 4√5 - √721
= 10√7 + 10√5 - √721

d.
2√150 - 3√54 - √294 + 3√486
= 2√(25x6) - 3√(9x6) - √(49x6) + 3√(81x6)
= 2(5√6) - 3(3√6) - 7√6 + 3.9√6
= 10√6 - 9√6 - 7√6 + 27√6
= 21√6

e.
√12 + √27 + √75
= √(4x3) + √(9 x 3) + √(25x3)
= 2√3 + 3√3 + 5√3
= 10√3
