Odpowiedź:

3²=3*3=9 5²=5*5=25 9²=9*9=81

(2/3)²= 2/3*2/3=4/9 (4/5)²=4/5*4/5=16/25

(8/9)²=8/9*8/9=64/81 (1,1)²=1,1*1,1=1,21

(1,2)²=1,2*1,2=1,44 (1,3)²=1,3*1,3=1,69

$3^2=3*3=9\\\\5^2=5*5=25\\\\9^2=9*9=81\\\\(\frac23)^2=\frac23*\frac23=\frac49\\\\(\frac45)^2=\frac45*\frac45=\frac{16}{25}\\\\(\frac89)^2=\frac89*\frac89=\frac{64}{81}\\\\(1.1)^2=\frac{11}{10}*\frac{11}{10}=\frac{121}{100}=1.21\\\\(1.2)^2=\frac{12}{10}*\frac{12}{10}=\frac{144}{100}=1.44$

$(1.3)^2=\frac{13}{10}*\frac{13}{10}=\frac{169}{100}=1.69$
