(4/5)2×(5)4×(2/5)-2÷(5/2)-3

​

Answer 1

Step-by-step explanation:

$( \frac{4}{5} )2 \times 5(4) \times ( \frac{2}{5} ) - 2 \div ( \frac{5}{2} ) - 3 \\ \frac{8}{5} \times 20 \times \frac{ - 4}{5} \div \frac{ - 15}{2} \\ = 32 \times \frac{ - 4}{5} \div \frac{ - 15}{2} \\ = \frac{ - 128}{5} \times \frac{ - 2}{15} \\ = \frac{256}{225} \\ = \binom{16}{15} ^{2} .$
