Partial Derivative (Calculus) question?

Here's the question/problem...

(NOTE, the "e" is that slanted/lowercase one that's equal to like 2.71...etc.)

f (x, t) = te^-(2xt)

...Find fx (x, t) and ft (x, t)

Show work. Fastest answer with correct answer gets best answer. Thank you!

    The partial of f with respect to x is (chain rule)

    (-2t) [te^(-2xt)] = -2t^2 e^(-2xt)

    The partial of f with respect to t is (product rule)

    (-2x) [te^(-2xt)] + (1)e^(-2xt)

    = (1 - 2xt) e^(-2xt)

    f(x,y) = x/(4 + y) = x(4 + y)^-a million so as that df/dx = a million/(4 + y) the place df/dx capacity differentiate f, in part, wrt x df/dy = -x/(4 + y)^2 the place df/dy capacity differentiate f, in part, wrt y
