481. 1) a⁵: a³; 4) c⁵: c⁴; 2) x⁷: x²; 5) m⁶: m²; 3) m⁷: m²; 6) p⁸: p⁴.

Решение:

1. \( \frac{a^5}{a^3} = a^{5-3} = a^2 \)
2. \( \frac{c^5}{c^4} = c^{5-4} = c \)
3. \( \frac{x^7}{x^2} = x^{7-2} = x^5 \)
4. \( \frac{m^6}{m^2} = m^{6-2} = m^4 \)
5. \( \frac{m^7}{m^2} = m^{7-2} = m^5 \)
6. \( \frac{p^8}{p^4} = p^{8-4} = p^4 \)

Ответ: 1) a²; 2) x⁵; 3) m⁵; 4) c; 5) m⁴; 6) p⁴.
