Prove by induction that mn then no injection
WebbMathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. It is done in two steps. The first step, known as … WebbAnswer (1 of 6): Prove it for n=1, then prove it for n+1 so it will hold for n. e.g. 2^(n - 1) when n = 1 its 1 while n! = 1, proved now, to prove for any n we fix this n as “k”, so n=k …
