Answer 1

Ответ:

$(4 \frac{1}{3} - 3 \frac{4}{9} {)}^{2} \times (2 \frac{1}{4} {)}^{2} = (3 \frac{12}{9} - 3 \frac{4}{9} {)}^{2} \times (\frac{9}{4} {)}^{2} = ( \frac{8}{9} {)}^{2} \times ( \frac{9}{4} {)}^{2} = \frac{8 \times 8 \times 9 \times 9}{9 \times 9 \times 4 \times 4} = \frac{2 \times 2}{1} = 4$
