I already answered this one today.
In general:
^n\ =\ \sum_{k=0}^n\,\left(n\cr k\right)\,x^{n-k}y^k)
^n\ =\ \sum_{k=0}^n\,(-1)^k\,\cdot\,\left(n\cr k\right)\,x^{n-k}y^k)
So the first four terms of your sum:
^{10}\ =\ \sum_{k=0}^{10}\,(-1)^k\,\cdot\,5^k\,\cdot\,\left(10\cr\ k\right)\,m^{10-k})
are:
Remember: \ =\ \frac{n!}{k!(n\,-\,k)!})
You can do the rest of the arithmetic, and don't forget to alternate the signs.
