Question 199744
{{{1.5e^(-1.9x)=1}}}
.
First get the x term on one side of the equation:
{{{e^(-1.9x)=1/1.5}}}
.
Take the ln of both sides:
{{{ln(e^(-1.9x))=ln(1/1.5)}}}
.
Use the log property to simplify the left side and use your calculator on the right side:
{{{-1.9x=-.405}}}
.
Solve for x and you are done:
{{{highlight(x=0.2134)}}}
.
