Problem 3.2.14a
show that 2^2x+1 +1 is divisible by 3.

The given expression is divisible by 3 for all natural values of x.

Step-by-step explanation:

The given expression is

For x=1,

9 is divisible by 3. So, the given statement is true for x=1.

Assumed that the given statement is true for n=k.

This expression is divisible by 3. So,

             .... (1)

For x=k+1

Using equation (1), we get

This expression is also divisible by 3.

Therefore the given expression is divisible by 3 for all natural values of x.
