(n^4)^5 / (8m)³ : (4m²)^5 / n = [n^(4·5) · n] / {[(2³)³·m³] ·[(2²)^5·(m²)^5] =
= (n^20 · n) /( 2^9 · 2^10 · m³ · m^10) =
= n^21 / (2^19 · m^13
(∛16ab)^12 / (∛[(2a)^4·b^9] =
=(2^4·ab)^(1/3·12) / [(2^4)^(1/3) ·(a^4)^(1/3) · b^(9·1/3)] =
(2^4)^1/3 сокращаются
= (a^4 · b^4)/ (a^(4/3) · b³ =
= a^(4-4/3) · b^(4-3) = a^(8/3) · b =
= (∛a)^8 · b
