-1 + log(3125)
--------------
5*log(5)
$$\frac{-1 + \log{\left(3125 \right)}}{5 \log{\left(5 \right)}}$$
-1 + log(3125)
--------------
5*log(5)
$$\frac{-1 + \log{\left(3125 \right)}}{5 \log{\left(5 \right)}}$$
-1 + log(3125)
--------------
5*log(5)
$$\frac{-1 + \log{\left(3125 \right)}}{5 \log{\left(5 \right)}}$$
-1 + log(3125)
--------------
5*log(5)
$$\frac{-1 + \log{\left(3125 \right)}}{5 \log{\left(5 \right)}}$$
(-1 + log(3125))/(5*log(5))
-1 + log(3125)
x1 = --------------
5*log(5)
$$x_{1} = \frac{-1 + \log{\left(3125 \right)}}{5 \log{\left(5 \right)}}$$
x1 = (-1 + log(3125))/(5*log(5))
