Question 64308
{{{((e^x)^4*e^5)/(e^(2x))=3}}}

{{{e^(4x)*e^5/e^(2x)=3}}}
{{{e^(4x+5-2x)=3}}}
{{{e^(2x+5)=3}}}
{{{ln(e^(2x+5))=ln(3)}}}
{{{(2x+5)ln(e)=ln(3)}}}
{{{(2x+5)(1)=ln(3)}}}
{{{2x+5=ln(3)}}}
{{{2x+5-5=ln(3)-5}}}
{{{2x=ln(3)-5}}}
{{{2x/2=(ln(3)-5)/2}}}
{{{x=(ln(3)-5)/2}}}  Put this in your calculator.
x~-1.950693856  Round off to whatever your asked for.
Happy Calculating!!!
