Объяснение:

(0,25a⁻⁴y⁻³)²·(a⁻³/(4y²))⁻³=1/(4²a⁸y⁶) ·4³y⁶a⁹=4³⁻²a⁹⁻⁸y⁶⁻⁶=4a·1=4a

(x⁻³y⁴/9)⁻²·(3/(x⁻²y³))⁻³=(3²x³/y⁴)²·(y³/3x²)³=3⁴x⁶/y⁸·y⁹/(3³x⁶)=3⁴⁻³x⁶⁻⁶y⁹⁻⁸=3·1y=3y

(m⁻⁴/(10n⁵k²))⁻²÷(5m²n³k)³=((2·5)²n¹⁰k⁴m⁸)÷(5³m⁶n⁹k³)=4·5²⁻³n¹⁰⁻⁹k⁴⁻³m⁸⁻⁶=(4m²nk)/5

(9c⁵/(a³b⁻²))⁻²÷(a²b⁻³/(6c⁴))³=a⁶/((3²)²c¹⁰b⁴)·(2·3)³c¹²b⁹/a⁶=a⁶⁻⁶·4·3³⁻⁴c¹²⁻¹⁰b⁹⁻⁴=1·4/3 ·c²b⁵=(4b⁵c²)/3
