Odpowiedź:
a)
√4/25 + √49/100 = 2/5 + 7/10 = 4/10 + 7/10 = 11/10 = 1 1/10
b)
√9/64 - √9/16 = 3/8 - 3/4 = 3/8 - 6/8 = -3/8
c)
√36/49 * √4/9 = 6/7 * 2/3 = 4/7
d)
√25/81 : √1/36 = 5/9 : 1/6 = 5/9 * 6 = 10/3 = 3 1/3
e)
√1/36 + √4/36 + √9/36 = 1/6 + 2/6 + 3/6 = 6/6 = 1
f)
√4/9 * √9/16 * √16/25 = 2/3 * 3/4 * 4/5 = 1/2 * 4/5 = 2/5
