17. Without using a calculator evaluate. 18. The lengths of three wires were \( 30 \mathrm{~m}, 36 \mathrm{~m} \) and 84 m . Pieces of wire of equal lenght were cat from the three wires. Calculate the least number of pieces obtained.

1) \( a=8 \frac{2}{5} \) vo \( b=1 \frac{1}{20} \) olduqda \( 0,2 \cdot(a: b) \) ifadosinin qiymotini tapın. 2) \( a=1 \frac{3}{23} \) vo \( b=4 \frac{5}{23} \) olduqda \( (b: a): 2 \frac{1}{2} \) ifadosinin qiymotini tapın.

Express 1728 and 2025 in terms of their prime factors. Hence evaluate \( \frac{\sqrt[3]{1728}}{\sqrt{2025}} \)
