Let P(n) be n!<nn and n is an integer greater than 1.
a) In the formula for P provided, change n to 2 (n).
P(2) states 2!<22
b)First of all
22<4=22
P(2) is then noted to be true.
c)A induction theory Suppose P(k) is true.
k!<kk
d) We must show that P(k+1) is  true.
(k+1)!<(k+1)k+1
e)We must demonstrate that P(k+1) is also true.
(k+1)(k+1)k!
<(k+1)kk
<(k+1)(k+1)k
=(k+1)k+1
=(k+1)k+1
 P(k+1) is also true.
f) Conculusion P(b) is true for all positive integers n greater than 1 according to the mathematical induction principle.
