Question 303465
Note: I'm assuming that the log is base 10.



{{{17 = 15 + 2*log(10,(x))}}} Start with the given equation.



{{{17 - 15 = 2*log(10,(x))}}} Subtract 15 from both sides.



{{{2 = 2*log(10,(x))}}} Combine like terms.



{{{2/2=log(10,(x))}}} Divide both sides by 2.



{{{1=log(10,(x))}}} Reduce.



{{{x=10^1}}} Convert to exponential form.



{{{x=10}}} Simplify.



So the solution is {{{x=10}}}
