Answer 1

1)2 + ∛m²/(∛m+2)=(2∛m+4+∛m²)/(∛m+2)=(∛m+2)²/(∛m+2)=∛m+2
2)∛m + 2∛m/(∛m-2)=(∛m²-2∛m+2∛m)/(∛m-2)=∛m²/(∛m-2)
3)(8-m)/(∛m+2) * 1/(∛m+2)=(8-m)/(∛m+2)²
4)∛m²/(∛m-2) *(∛m-2)(∛m+2)/[∛m(∛m+2)]=∛m
5)(8-m)/(∛m+2)²+ ∛m=(8-m+m+2∛m²+4∛m)/(∛m+2)²=
=(8+2∛m²+4∛m)/(∛m+2)²=4(∛m²+2∛m+4)/(∛m+2)²=
=2(∛m+2)²/(∛m+2)²=2
