Odpowiedź:
(54x³-27x²)(1-9x) =(54*(1/3)³-27*(1/3)²)(1-9*1/3)=(54*1/27 -27*1/9)(1-3)=(2-3)*(-2)=(-1)*(-2)=2
Szczegółowe wyjaśnienie:
[tex](54 \times { (\frac{1}{3} })^{3} - 27 \times { (\frac{1}{3} })^{2} )(1 - 9 \times \frac{1}{3} ) \\ (54 \times \frac{1}{27} - 27 \times \frac{1}{9} )(1 - 3) \\ (2 - 3)(1 - 3) = ( - 1) \times ( - 2) = 2[/tex]
