Помогите ето решить пожалуста мне нужно бистро​

Answer 1

4.

A) x⁷ * x⁴ = x⁷⁺⁴ = x¹¹

Б) x⁷ / x⁴ = x⁷⁻⁴ = x³

B) (x⁷)⁴ = x ⁷ ˣ ⁴ = x²⁸

Г) (x³)⁶ * x¹⁴ / x¹⁸ = x³ˣ⁶ * x¹⁴ / x¹⁸ = x¹⁸ * x¹⁴ / x¹⁸ = x¹⁸⁺⁴⁻¹⁸ = x¹⁴

5.

A) 2¹⁰ * 32³ / 8⁷ = 2¹⁰ * (2⁵)³ / (2³)⁷ = 2¹⁰ * 2¹⁵ / 2²¹ = 2¹⁰⁺¹⁵⁻²¹ = 2²⁵⁻²¹ = 2⁴ = 16

Б) (2 (1/3))⁷ * (3/7)² = (7/3)⁷ * (3/7)² = (7*7*7*7*7*7*7 / 3*3*3*3*3*3*3) * (7*7 / 3*3) = 7*7*7*7*7*7*7*3*3 / 3*3*3*3*3*3*3*7*7 = 7*7*7*7*7 / 3*3*3*3*3 = (7/3)⁵ = (2 (1/3))⁵

6.

A) -5x³y² * 4x⁷y = -5*4*x³⁺⁷*y²⁺¹ = -20x¹⁰y³

Б) (-2x²y⁵)³ = - 2³ x²ˣ³ y⁵ˣ³ = -8x⁶y¹⁵
