n is an element of the Natural numbers, and n [itex]\geq5[/itex], then 4^n [itex]\geq(n^4)[/itex]
Base case: n=5, then 4^5=1024 >or= 5^4=625 as required.
The Attempt at a Solution
Inductive step, assume k is an element of Natural numbers and 4^k > or = k^4.
Then we must show 4^(k+1) > or = (K+1)^4
What's the trick to showing this?
