And then what do we have here? I can just rewrite that. This is continuing the same line. 1 minus lambda over n to the n times 1 minus lambda over n to the minus k. Now we can take the limit. So what happens when we take the limit? So just so you know, if you take the limit, this is another property, just so you don't get too overwhelmed. Another property of limits, if I take the limit as x approaches anything, a of f of x times g of x, that's equal to the limit as x approaches a of f of x times the limit as x approaches a of g of x.
