It looks like the limit you want to find is
One way to compute this limit relies only on the definition of the constant e and some basic properties of limits. In particular,
The idea is to recast the given limit to make it resemble this definition. The definition contains a fraction with x as its denominator. If we expand the fraction in the given limand, we have a denominator of x - 1. So we rewrite everything in terms of x - 1 :
Now in the first term of this product, we substitute y = (x - 1)/5 :
Then use a property of exponentiation to write this as
In terms of end behavior, (x - 1)/5 and x behave the same way because they both approach ∞ at a proportional rate, so we can essentially y with x. Then by applying some limit properties, we have
By definition, the first limit is e and the second limit is 1, so that
You can also use L'Hopital's rule to compute it. Evaluating the limit "directly" at infinity results in the indeterminate form
.
Rewrite
so that
and now evaluating "directly" at infinity gives the indeterminate form 0/0, making the limit ready for L'Hopital's rule.
We have
and so
