Calculus question...help, please?

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!

Update:

Sorry, I messed up. The actual function was f (x, t) = te^-(2xt) ...there was a negative. My bad. Can you redo the work/answer? Greatly appreciated!! Thanks! And yes, this is via partial derivative.

    Assuming that fx means partial derivative with respect to x,

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

    fx = te^(2xt) *2t

    fx = 2t^2 * e^(2xt_

    ft = 1*e^(2xt) + e^(2xt)*2x

    ft = (2x+1) * e^(2xt)
