    How to solve these derivatives problems?

    Question says-

    find the derivatives of: d/dt t^(-pi^2)
    Steps:
    have no clue how to do this.



    And then find the equation of the tangent line to y=4e^x at x=2?

    Steps: derivative of y= 4e^x. Plug 2 in for x and then I find the slope of the tangent line which is 29.556

    Then to find the equation I have slope m, and x=2. How do I find y to find the equation?

    Please help!!

    know how to use the power rule?

    if x = 2, y = 4e^2
    btw ... this is "pie"



    this is pi ...
