If `x^(-(p/q))=(1/x)^(k)` then `k=` ________.

If ((x^(m)xx x^(n))/x^(p))^(q)=x^(k) , then k= ________.

If a^(p/q)=root(q)(k) , then k= _______.

For a random variable X if P(X=k) = 4((k+1)/5^k)a , for k=0,1,2,…then a= _____

p(x) = x^(2)-x+k, p(1) = -1 then k = …………

If p is nearly equal to q and n gt 1 , such that ((n+1) p+(n-1)q)/((n-1)p+(n +1)q) = ((p)/(q))^(k) , then the value of k, is

If p is nearly equal to q and n gt 1 , such that ((n+1) p+(n-1)q)/((n-1)p+(n +1)q) = ((p)/(q))^(k) , then the value of k, is
