b)
√(121/144) = √11²/√12² = 11/12
√(361/400) = √19²/√20² = 19/20
√(576/625) = √24²/√25² = 24/25
c)
√2 * √8 = √(2 * 8) = √16 = √4² = 4
√6 * √1,5 = √(6 * 1,5) = √9 = √3² = 3
√2 * √5 * √10 = √(2 * 5 * 10) = √100 = √10² = 10
d)
√54/√6 = √(54/6) = √9 = √3² = 3
√3/√12 = √(3/12) = √(1/4) = √(1/2)² = 1/2
(√10 * √14)/√35 = √(10 * 14)/√35 = √140/√35 = √(140/35) = √4 =
= √2² = 2
