Expert Answer
Let P(n): 3n < 4n for all n 
N.
N.P(1): 3 < 4, which is true. Thus P(n) is true for n = 1.
Let P(k) be true for some natural number k
i.e. 3k < 4k
Now we prove that P(k +1) is true whenever P(k) is true.
Thus P(k +1) is true whenever P(k) is true.
By principle mathematical induction 3n < 4n for all n N.
