Jawaban:

$a. sqrt{125} = sqrt{25 times 5} = 5 sqrt{5} \ \ b. sqrt[]{600} = sqrt{100 times 6} = 10 sqrt{6} \ \ c. sqrt{0.000256 } \ = sqrt{ frac{256}{1.000.000} } \ = frac{16}{1000} = 0.016 \ \ d. sqrt[5]{3} + sqrt{243 } - sqrt[]{12} \ = sqrt[5]{3} + sqrt{81 times 3} - sqrt{4 times 3} \ = sqrt[5]{3} + 9 sqrt{3} - 2 sqrt{3} \ = 7 sqrt{3} + sqrt[5]{3}$
