yeah. bc im supposed to solve for t.

is the 24 supposed to be used as a constant? or when i use product rule do i just use the 24t by itself for the product rule?

24(t x e^-2.2t  + ( e^-2.2t x 1)

what do i do with the -2.2?? do i bring that down in front of the e. so it would be -2.2e^-t?

im just confused.

A electron moving along the x axis has a position given by x = 24 te^-2.2 t m, where t is in seconds. How far is the electron from the origin when it momentarily stops?

i belive im supposed to use the product rule. but i cannot seem to get the correct answer.
can some please walk me through it. thanks in advance.
