1) nesubunitare?
subunitare numarator mai mic decit numitor
daca sunt nesubunitare atunci pot fi:
supraunitare.....adica numarator mai mare numitor
echiunitare numarator= numitor
2)
5³=125 [tex]= \frac{125}{125} [/tex]
6³=216⇒ [tex]= \frac{216}{216} [/tex]
7³=343⇒ [tex]= \frac{343}{343} [/tex]
8³=512⇒ [tex]= \frac{512}{512} [/tex]
9³=729⇒ [tex]= \frac{729}{729} [/tex]
3) sunt patrate perfecte de 2 cifre: 16,25,36,49,64 si 81
[tex]16/25; 16/36; 16/49; 16/64; 16/81[/tex]
[tex]25/36; 25/49; 25/64; 25/81[/tex]
[tex]36/49; 36/64; 36/81[/tex]
49/64; 49/81
64/81
