a) (1/6 x⁻⁴y³)⁻¹ = (1/6)⁻¹ * (x⁻⁴)⁻¹ * (y³)⁻¹ = 6 * x⁴ * y⁻³ = 6x⁴/y³
Ответ: 6x⁴/y³
б) (3a⁻⁴ / 2b⁻³)⁻² * 10a⁷b³ = (3a⁻⁴)⁻² / (2b⁻³)⁻² * 10a⁷b³ = 3⁻² * (a⁻⁴)⁻² / (2⁻² * (b⁻³)⁻²) * 10a⁷b³ = (1/9) * a⁸ / ((1/4) * b⁶) * 10a⁷b³ = (4/9) * a⁸ / b⁶ * 10a⁷b³ = (40/9) * a⁸⁺⁷ * b³⁻⁶ = (40/9) * a¹⁵ * b⁻³ = (40a¹⁵) / (9b³)
Ответ: (40a¹⁵) / (9b³)
