Ответ:

  1. \(875=5\cdot175=5^2\cdot35=5^3\cdot7\).
  2. \(2376=8\cdot297=2^3\cdot3^3\cdot11\).
  3. \(5625=75^2=(3\cdot5^2)^2=3^2\cdot5^4\).
  4. \(2025=45^2=(3^2\cdot5)^2=3^4\cdot5^2\).
  5. \(3969=63^2=(3^2\cdot7)^2=3^4\cdot7^2\).
  6. \(13125=125\cdot105=5^3\cdot3\cdot5\cdot7=3\cdot5^4\cdot7\).

Ответ: а) \(875=5^3\cdot7\); \(2376=2^3\cdot3^3\cdot11\); \(5625=3^2\cdot5^4\). б) \(2025=3^4\cdot5^2\); \(3969=3^4\cdot7^2\); \(13125=3\cdot5^4\cdot7\).
