√2 * √72 = √(2 * 72) = √144 = 12
√63/√7 = √(63/7) = √9 = 3
3√4 * 3√54 = 3 * 3 * √(4 * 54) = 9√216 = 9√(36 * 6) = 9 * 6√6 = 54√6
√9 + √16 = 3 + 4 = 7
3√1250/3√10 = √(1250/10) = √125 = 15
√169 - √144 = 13 - 12 = 1
√17 * √17 = √17² = 17
(√11)² = √11² = 11
√7² = 7
(3√30)³ = 27√30³ =27 * 30√30 = 810√30
3√5 * 3√5 * 3√5 = 3 * 3 * 3√(5 * 5 * 5) = 27 * 5√5 = 135√5
