e^x+2=13

solve by logarithm

Take the ln of both sides.
x*ln e = ln 13.
You can do this on your calculator. If you don't know the value of e, go to www.google.com and type in e and search. The value is about 2.7.

or type this in the google search window
ln(13) / ln(e)

    using logarithms to solve exponential equations. 5^1+x = 2^1-x I need exact numbers. I did one on my own already. 5^x-1 = 9 5^x-1 = 9 log(5^x-1) = log9 (log5)(x-1) = log9 x-1 = (log9/log5) x= (log9/log5)-1 x = 2.3652 Logarithm
