Algebra: Big negative powers and numbers....

Question

I have a problem with a mathematical problem that I know that I have to use some "power properties" but this problem confuses me and I can't solve it. Here is the problem: $$ (-4)^{-60} \cdot (1{,}25)^{-40} \cdot 10^{-41} $$

I've assumed that "1,25" is continental notation for 1.25... let me know if you intended something different. — user7530, Oct 09 '17 at 20:40
@user7530 Yep. That what i mean. But i live in Europe, Greece and we use , and not . In decadical numbers. — Alex Kordatzakis, Oct 09 '17 at 20:43

Hint: Use the facts that $-4=(-1)\cdot4$ and $1.25=\frac{5}{4}$.

Ok. I will "play" with maths now a little bit. Thanks – Alex Kordatzakis Oct 09 '17 at 20:54
