# Math Help - how to finish this proof

1. ## how to finish this proof

|(n^2 +10)/(n^3 -10)|<(n^2 +10)/(n^3)< ..<e

i need some (1/n)<e

??

2. Hi,

We have $\frac{n^2 +10}{n^3}=\frac{n^2}{n^3}+\frac{10}{n^3}=\frac{1}{ n}+\frac{10}{n^3}$ therefore...

3. i need to find an expression which is bigger then what you showed
and has "n" in power 1
in the dominator

4. i got

n>10/(e-1)

what to write about N ??
