To express (39 \times 5) using the distributive property, you can break down 39 into two parts, such as 30 and 9. This gives you (39 \times 5 = (30 + 9) \times 5). Applying the distributive property, you can rewrite it as (30 \times 5 + 9 \times 5), which simplifies to (150 + 45), resulting in (195).
