[(125)^3.5^5-(25)^7]:2004²⁰⁰⁵ = ?

Answer 1

[Le Thi Khanh Huyen]

\(\left(125^3.5^5-25^7\right):\frac{2004}{2005}\)

\(=\left[\left(5^3\right)^3.5^5-\left(5^5\right)^7\right].\frac{2005}{2004}\)

\(=\left(5^9.5^5-5^{14}\right).\frac{2005}{2004}\)

\(=\left(5^{14}-5^{14}\right).\frac{2005}{2004}\)

\(=0.\frac{2005}{2004}=0\)
