Răspuns:
Explicație pas cu pas:
a)
√1/9 = 1/3
√81/25 = 9/5
√169/4 = 13/2
√625/289 = 25/17
√3/300 = √1/100 = 1/10
_____________
b)
√25/9 = 5/3
√9/4 =3/2
√121/36 = 11/6
√225/49 = 15/7
√529/100 = 23/10
______________
c)
√0,81 = √81/100 = 9/10 = 0,9
√0,16 = √16/100 = 4/10 = 0,4
√1,96 = √196/100 = 14/10 = 1,4
√4,41 = √441/100 = 21/10 = 2,1
√20,25 = √2025/100 = 45/10 = 4,5

d)
√2^4/3^6 = 2^2/3^3 = 4/27
√3^4*5^6/7^2 = 3^2*5^3/7 = 9*125/7 = 1125/7
√12/3^3*4^3 = √12/12^3 = √1/12^2 = 1/12
√(9 + 16)/(49 + 576) = √25/625 = 5/25 = 1/5
