1) a) (-a)² * a⁵ = a² * a⁵ = a⁷
б) -a² * a⁵ = -a⁷
в) a² * (-a)⁵ = -a⁷
г) (-a²) * (-a)⁵ = a⁷
2) a) (x³)² * x⁴ = x⁶ * x⁴ = x¹⁰
б) (x³ * x⁵)⁴ = (x⁸)⁴ = x³²
в) x³ * (x³)³ = x³ * x⁹ = x¹²
г) (x * x⁵)⁵ = (x⁶)⁵ = x³⁰
3) a) (y³)² * (y²)³ = y⁶ * y⁶ = y¹²
б) (y³ * y)³ * (y³ * y)² = (y⁴)³ * (y⁴)² = y¹² * y⁸ = y²⁰
в) (y⁶)² * (y⁴ * y²)² = y¹² * (y⁶)² = y¹² * y¹² = y²⁴
4) a) c¹⁰ : (c²)⁵ = c¹⁰ : c¹⁰ = 1
б) (c³)⁷ : (c³)⁶ = c²¹ : c¹⁸ = c³
в) (c² * c)³ : (c³ * c)² = (c³)³ : (c⁴)² = c⁹ : c⁸ = c
