Using contrapositive method prove that , if `n^(2)` is an even integer, then n is also an even integer.

Using permutation or otherwise, prove that (n^2)!/(n!)^n is an integer, where n is a positive integer. (JEE-2004]

In n is an even integer, which one of the following is an odd integer?

Write all even integers between -9 and 6.

Check whether the following statement is true or not: p : If \ x\ a n d\ y are odd integers, then x+y is an even integer.

Prove that 2^n > n for all positive integers n.

Write all even integers between -11and8 .

If n is an even positive integer, then a^(n)+b^(n) is divisible by

Write all even integers between (-4) and 11

Show that the following statement is true by the method of contrapositive. P: If x is an integer and x^(2) is even, then x is also even.

Show that the following statement is true by the method of contrapositive. p: If x is an integer and x^2 is even, then x is also even.
