ln both sides: ln(10^x)=ln(5) simplify: ln(10)x=ln(5) divide: x= ln(5)/ln(10)

OpenStudy (anonymous):

what is ln?

OpenStudy (anonymous):

the natural log

OpenStudy (anonymous):

so its 5/10?

OpenStudy (anonymous):

it says exact solution set and rounded solution set

OpenStudy (anonymous):

umm no it is the natural log of 5 divided by the natural log of 10. The number is something like 0.6989700043360188047862611052755069732318101185378914. Are you sure this is the problem you were asked?
