Find the derivative of the given function.
1.) y = (x ^ 3 - 3)(x ^ 2 + 4x + 1)
2.) y = (7x + 3)(x ^ 4 - x ^ 3 - 9x)
3.) y = x ^ 2 * (2x ^ 2 + x + 1)
4.) y = (x ^ 2 - 10x + 2)(x ^ 3 - 2x ^ 2 + 1)
5.) y=(x^ 2 -2x-1)(x+)
6.) y= sqrt x( x^ 3 -2x^ 2 +7x-1)
7.) t = x ^ (1/3) * (x ^ 2 - 5x + 2)
8.) y = (5x ^ 2 - 13)(x ^ 3 + 6x + 1)
9.) y=x^ -2 (x^ 2 +7
10.) x ^ - 5 * (x ^ 2 + 10x - 5)
