    Differentiate the function:

    f(x) = 4/5(x^5 + x)

    f(x) = 4/5x^5 + 4/5x

    f'(x) = 4x^4 + 4/5 answer//

    Differentiate the function:

    f(t) = - 2/[7t^(-5)] + 6t^3

    f(t) = -2/7t^5 + 6t^3

     f'(t) = - 10/7t^4 + 18t^2 answer//

    f(x) = (4/5)(x^5 +x).

    f'(x) = (4/5)(5x^4 +1).

    f(t) = -2/7t^(-5) +6t^3 = (2/7)t^5 + 6t^3.

    f'(t)=(2/7)(5t^4) +6(3t^2)= (10/7)t^4 +18t^2 =                        (1/7)t^2(10t^2 + 7*2*9) = (2/7)t^2(5t^2 + 63).

    f'(x)= 4x^4 + 4/5

    f'(t)= (10/7)t^4 + 18t^2
