Question 108810
{{{10^x= 1000}}} 
{{{log((10^x))=1og(1000)}}} Log of both sides. 
{{{x=3}}} 
My answer is 3.
Correct.
{{{10^(2x+1) =3}}}
{{{log((10^(2x+1)))=log(3)}}}Log both sides.
{{{2x+1= .4771}}}
{{{2x= -.5229}}}Subtract 1 from both sides and divide by 2.
{{{x=-.2614}}}
My answer is x=.2385 
Incorrect.
{{{e^(3y)=1}}}
{{{ln(e^(3y))=ln(1)}}}Natural log of both sides. 
{{{3y=0}}}Divide by 3.
{{{y=0}}}
My answer is x=.7675 
Incorrect.
