Question 841176
I'm going to use the rule 


{{{e^x=y}}} ----> {{{x = ln(y)}}}


to get...


{{{e^(4x)=110}}}


{{{4x=ln(110)}}}


{{{x=ln(110)/4}}} <font color="red"><--- Exact Answer</font>


{{{x=1.1751200914481}}} <font color="blue"><--- Approximate Answer</font> (use a calculator and follow any rounding rules given)
