Find the median of the exponential random variable with parameter λ=0.15

Solve $\int_0^{m} f(x) \, dx = \frac{1}{2}$ for $m$ , where $m$ is the median (I refuse to use $\mu$ as the symbol for the median - using this symbol is plain dumb) and $f(x)$ is the pdf of the exponential random variable.

If you need more help, please show all your working and say where yu get stuck.
