Please help me solve question 7 Thank You!

8 7. * Let u, v be functions of x. The first order derivative of uv can be obtained by the product rule: ( 20)' = uv + uv'. The general formula for n-th order derivative of uv was derived by the German mathematician Gottfried Wilhelm Leibniz: n ( 20) (7 ) = n LU ( * ) u ( n - k ) K= 0 where n! the symbol u(k) = dku dack means the k-th order derivative of u and u(0) = u. By Leibniz's formula, compute f(100) (x) if f(x) = (213 +5x2 - x+ 3) cos
