Answer 1

Answer:

Step-by-step explanation:

using PMI to prove.

Putting n =1

49+16-1=64 (which is obviously divisible by 64.

Hence the expression is valid for n=1

So the expression will be valid for n=k

(m be any natural no.) ------------(1)

Now to prove that the expression is valid for any value of n,we need to prove that the expression is valid for n=k+1 also.

To prove:

b is any natural number.
