**proof by mathematical induction**

subject is PreCalulus. 2^(k+3) = and < (k+3)! i know how to do proving using mathematical induction when its just an equal sign, but I dont understand what to do when its an inequality. thank you!!! Here is what I would do Step 1: check if it is true for k=1 that is: let k=...
