if `f(x) = x^n` then the value of `f(1) - (f'(1))/(1!) + (f''(1))/(2!) + ---+((-1)^n f''^--n times (1))/(n!)`

if f(x)=x^(n) then the value of f(1)-(f'(1))/(1!)+(f''(1))/(2!)+--+((-1)^(n)f^(prime--n)xx(1))/(n!)

If f(x) , x^n , then the value of f(1) = (f'(1))/(1!) + (f''(1))/(2!) - (f'''(1))/(3!) + ….+ (((-1)^n f^n (1))/(n!))

If f(x)=x^(n),"n" epsilon N , then the value of f(1)-(f^(')(1))/(1!)+(f^('')(1))/(2!)-(f^(''')(1))/(3!)+…+(-1)^(n)(f^(n)(1))/(n!) is
