1) ...=5^2/3 * 3^2/3 *3^7/3 / 5^(-1/3) = 5^ (2/3+1/3) * 3^(2/3 + 7/3) = 5^1 * 3^3 = 5*27=135
2) ...= 25/16 - 1/3 +4*1=41/16-1/3=107/48
3) ...= ∛(128/2)+ ∛(1/4 :2)= 4+0,5=4,5

1) ... = ∛(ab²a^5 *b / c*c²) = ∛(a^6 *b³ / c^3) = a²b/c
2) ...= a^(-3+7/3 - 1/3)=a^-1 = 1/a
3.
...= √a(√a-9) / 7(a^(1/4) +3)=√a(a^(1/4) - 3) / 7
5.
....=(∛a+∛b+∛a-∛b)(∛a+∛b-∛a+∛b)=2∛a *2∛b
