`n^(2)-1` is divisible by 8, if n is (A) an integer (B) a natural number (C) an odd integer (D) an even integer

If (12^(n)+1)backslash is divisible by 13, then n is (a) 1 only (b)12 only (c) any odd integer (d) any even integer

Show that n^(2)-1 is divisible by 8, if n is an odd positive integer.

Show that n^2-1 is divisible by 8, if n is an odd positive integer.

If n is an odd integer, prove that n^(2) is also an odd integer.

If n is a positive integer, then (sqrt(3)+1)^(2n)-(sqrt(3)-1)^(2n) is (1) an irrational number (2) an odd positive integer (3) an even positive integer (4) a rational number other than positive integers

If n is a positive integer,then (sqrt(3)+1)^(2n)-(sqrt(3)-1)^(2n) is (1) an irrational number (2) an odd positive integer (3) an even positive integer (4) a a rational number other than positive integers

If n is a positive integer, then (sqrt(3)+1)^(2n)-(sqrt(3)-1)^(2n) is (1) an irrational number (2) an odd positive integer (3) an even positive integer (4) a rational number other than positive integers

If the number (1-i)^n/(1+i)^(n-2) is real and positive then n is (a) Any Integer (b) Any odd Integer (c) Any even Integer (d) None of these

(x+1) is a factor of x^(n)+1 only if n is an odd integer (b) n is an even integer n is a negative integer (d) n is a positive integer

If (4+sqrt(15))^n=I+f, where n is an odd natural number, I is an integer and ,then a. I is an odd integer b. I is an even integer c. (I+f)(1-f)=1 d. 1-f=(4-sqrt(15))^n
