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

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

If f(x)= (x^m)^(1/n) ,n in N , is an even function, then m is (a)even integer (b) odd integer (c) any integer (d) f(x)-e v e ni s not pos s i b l e

If f(x)= (x^m)^(1/n) ,n in N , is an even function, then m is (a)even integer (b) odd integer (c) any integer (d) f(x)-e v e ni s not pos s i b l e

If f(x)=root(n)(x^(m)),n in N, is an even function, then m is even integer (b) odd integer any integer (d)f(x)- even is not possible

If f(x)=x^m n ,n in N , is an even function, then m is even integer (b) odd integer any integer (d) f(x)-e v e ni snotpos s i b l e

If f(x)=x^m n ,n in N , is an even function, then m is even integer (b) odd integer any integer (d) f(x)-e v e ni snotpos s i b l e

If f(x)=^nsqrtx^m ,n in N , is an even function, then m is (a)even integer (b) odd integer any integer (d) f(x)-e v e n i s not pos s i b l e

Find the least positive integer n such that ((2i)/(1+i))^(n) is a positive integer.

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

The smallest positive integer n for which ((1+i)/(1-i))^n=1 is (a) 8 (b) 16 (c) 12 (d) None of these
