Let P(n) be the statement "3" = 1". The domain consists of all
non-negative integers.
A proof of VnP(n) is as follows:
(i) P(0) is clearly true.
(ii) Assume that P(0),.
...., P(k) are true for some non
negative integer k.
(iii) We have:
3+1=32k/3k1= 3* .3k/3k-1 = 1.1/1=1. Thus P(k+1) is
true. By strong induction, we conclude VnP(n).
Which step is wrong in this proof?
