La solución x=1 se puede encontrar reescribiendo la ecuación original
2^x . 5^x^2 = 2.5 , de ahi se deduce x=1

There's a notation error at the "x-1 (x log 5 + log 10) = 0" line. It's important to keep the "x-1" in parentheses. Apart from that... very nice!

Take the log on both sides, which is xlog(2)+x^2log(5)=1. Turn this into a quadratic equation, which is x^2log(5)+xlog(2)-1=0. From there, we need to convert everything with the same log. The LCM of 2 and 5 is 10. Therefore, we can either change log(2)=1-log(5) or log(5)=1-log(2). I'll go with the conversion of log(5)=1-log(2). x^2log(5)+x(1-log(5))-1=0. Turn this into a quadratic formula, which is Simplifying this value will give us The value for x is (2log(5))/(2log(5))=1 and

the sumnail is wrong. There is 6 instead of 5.
