3.303 Представьте в виде произведения степень: a) (3 + c)⁴; б) (b – 4)²; в) (x + y)²; г) (a – b)³.

a) (3 + c)⁴ = (3 + c) × (3 + c) × (3 + c) × (3 + c)

б) (b – 4)² = (b – 4) × (b – 4)

в) (x + y)² = (x + y) × (x + y)

г) (a – b)³ = (a – b) × (a – b) × (a – b)

Ответ:

a) (3 + c)⁴ = (3 + c) × (3 + c) × (3 + c) × (3 + c)
б) (b – 4)² = (b – 4) × (b – 4)
в) (x + y)² = (x + y) × (x + y)
г) (a – b)³ = (a – b) × (a – b) × (a – b)
