mam problem z taka granica | jesli mozna prosilbym powoli  | |
| n3(1+7√n+2) |
| (√n(√1 + 1/n + 1)7 | |
= | |
| n3 * √n(1/√n + 7√1 + 2/n) |
| √n7(√1 + 1/n + 1)7 | ||
= | = | |
| n3 * n1/2(1/√n + 7√1 + 2/n) |
| n7/2(√1 + 1/n + 1)7 | |
= | |
| n7/2(1/√n + 7√1 + 2/n) |
| (√1 + 1/n + 1)7 | (√1 + 0 + 1)7 | ||
→ | = | ||
| 1/√n + 7√1 + 2/n | 0 + 7√1 + 0 |
