Question

Solve for x: ln(2x + 2) = 5. Give answer rounded off to 3 decimal places.

Answer 1

make each side a power to the base "e"

then use the rule
\[ e^{\ln(x)} = x \]
to simplify the left side. what do you get ?

Answer 2

\[\ln(2x+2)=5<=> \ln(2x+2)=5*\ln(e)<=>\ln(2x+2)=\ln(e^{5})=>2x+2=e^5=>\]
\[x=\frac{ e^5-2 }{ 2 }\]

Answer 3

do you got it @suwhitney
