If f(x) =x^n and if f’ (1) = 10, find n.

In the expansion of (x^(3)-(1)/(x^(2)))^(n),n in N if sum of the coefficients of x^(5) and x^(10) is 0 then n is

In the expansion of (x^3-1/x^2)^n, n in N if sum of the coefficients of x^5 and x^(10) is 0 then n is

In the expansion of (x^3-1/x^2)^n, n in N if sum of the coefficients of x^5 and x^(10) is 0 then n is

For X ~ B (n,p), n = 10, E (X) = 5, then p =

We define a function f on the integers f(x) = x//10 , if x is divisible by 10, f(x) = x + 1 , if x is not divisible by 10. If A_(0) = 1994 and A_(n+1) = f(A_(n)) . What is the smallest n such that A_(n) = 2 ?
