7s over 5t to the negative 3rd power

2 to the negative 3rd power times X to the 2nd power times Z to the negative 7th power

7s to the zero power times T to the negative 5th power over 2 to the negative 1st power times M to the 2nd power

If you would please simplify these problems as much as you can.

Thanks
