a)
√40 000 = √(4*10 000) = 2 * 100 = 200
b)
√14 400 = √(144*100) = 12 * 10 = 120
c)
√640 000 = √(64*10 000) = 8 * 100 = 800
d)
√625 = √(25*25) = 5 * 5 = 25
e)
√44 100 = √(4 * 11025) = 2 * 105 = 210
f)
√4096 = √(4*1024) = 2 * 32 = 64
15.
√4,41/√0,01 = √441 = 21
√810 000/√10 000 = √81 = 9
(√500 * √2) : √10 = √1000/√10 = √100 = 10
(√4 + √25/36)/(√4 * √25/36) = (2 + 5/6)/(2 * 5/6) = 2 5/6 : 5/3 = 17/6 * 3/5 =
= 17/2 * 1/5 = 17/10 = 1,7
