Question

Determinati fractiile de forma a supra b , unde a este cub perfect de o cifra,iar b este patrat perfect de o cifra.

Answer 1

a=1;2

1³=1
2³=8

b=1,2,3

1²=1
2²=4
3²=9

a/b= 1/1=1
1/4=0.2
1/9=0,(1)

8/1=9
8/4=2
8/9=0,(8)

Answer 2

1^{3}/1^{2}=1/1.... 1^{3}/2^{2}=1/4.... 1^{3}/3^{2}=1/9.... 2^{3}/1^{2}=8/1.... 2^{3}/2^{2}=8/4.... 2^{3}/3^{2}= 8/9
