Question

prove that square of any odd number is a odd number​

Answer 1

Answer:

Proof: Let x be an arbitrary odd number. By definition, an odd number is an integer that can be written in the form 2k + 1, for some integer k. This means we can write x = 2k + 1, where k is some integer. ... Since this logic works for any odd number x, we have shown that the square of any odd number is odd.

Answer 2

Step-by-step explanation:

We can prove it by a simple example.

For example, 3 is an odd number.

Hence, the square of three (3*3) is 9.

And 9 is also an odd number.

Thus, the statement is proved correct.
