Question

Solve the equation. Give an approximate solution to four decimal places :: e(x + 4) = 6

A) 2.3026
B) -2.1282
C) -2.2082
D) -1.6974

Answer 1

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

Answer 2

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

Answer 3

expanding it would give you

ex + e4 = 6

Answer 4

do not expand

Answer 5

divide both sides by e, then minus 4

Answer 6

so you have

x + 4 = 6/e

x = 2/e ?

Answer 7

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

Answer 8

x+4 should be the power of e

Answer 9

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

Answer 10

C) -2.2082

Answer 11

hoblos, how did you get that?

Answer 12

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

Answer 13

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

Answer 14

THANKS!

Answer 15

welcome :D

Answer 16

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