 (23)2 \left(\frac{2}{3}\right)^2\  heeft als uitwerking:

 2232=46=23\frac{2^2}{3^2}=\frac{4}{6}=\frac{2}{3}  

 (23)(23)=2+23+3=46=23\left(\frac{2}{3}\right)\cdot\left(\frac{2}{3}\right)=\frac{2+2}{3+3}=\frac{4}{6}=\frac{2}{3}  

 (23)(23)=2233=49\left(\frac{2}{3}\right)\cdot\left(\frac{2}{3}\right)=\frac{2\cdot2}{3\cdot3}=\frac{4}{9}  

 2232=49\frac{2^2}{3^2}=\frac{4}{9}
