lilg132 · Answer

e(x+4) = 6 are you sure you wrote that correct?

anonymous · Answer

yeah. i just double checked and that's what it says....

lilg132 · Answer

expanding it would give you

ex + e4 = 6

anonymous · Answer

do not expand

anonymous · Answer

divide both sides by e, then minus 4

lilg132 · Answer

so you have

x + 4 = 6/e

x = 2/e ?

anonymous · Answer

but I think the problem should be e^(x+4)=6

anonymous · Answer

x+4 should be the power of e

anonymous · Answer

okay. it doesnt look like that in the document i was sent but i think you're right.

C) -2.2082

anonymous · Answer

hoblos, how did you get that?

hoblos · Answer

e(x+4) = 6
=> x+4 = ln6
=> x = ln6 - 4 = -2.2082

hoblos · Answer

btw e(x+4) is e^(x+4)

anonymous · Answer

THANKS!

hoblos · Answer

welcome :D

anonymous · Answer

$$e^{x+4}=6$$
$$x+4=\ln(6)$$
$$x=\ln(6)-4$$ then a calculator
