how do i start this problem? will give medals! e^(1 − 3x) = 4

Nnesha (nnesha):

to cancel out e you should take `ln` both sides

OpenStudy (x3_drummerchick):

do i take ln of both sides

OpenStudy (x3_drummerchick):

okay because it cancels out e, then what?

Nnesha (nnesha):

\[\cancel{ln e}^2 =2\]

Nnesha (nnesha):

then simplify (solve for x)

OpenStudy (x3_drummerchick):

would it be 1-3x = ln 4?

Nnesha (nnesha):

yes right !

OpenStudy (x3_drummerchick):

so( ln 4 - 1) / -3 ?

Nnesha (nnesha):

looks good

OpenStudy (x3_drummerchick):

for some reason, i keep putting that in and it keeps saying my answer is wrong in my online assignment

Nnesha (nnesha):

what's ur final answER ?

OpenStudy (x3_drummerchick):

OpenStudy (x3_drummerchick):

Nnesha (nnesha):

OpenStudy (x3_drummerchick):

i think im putting it in wrong

Nnesha (nnesha):
