ryan: powers of decimal
Hi Ryan,
If you are allowed to use a calculator you can just opt for pressing buttons but if you want/need to understand then
powers of decimals is just multiplying decimals
0.2
3 = 0.2 * 0.2 * 0.2
so if you can understand multiplying decimals then you can work out powers of decimals
To that end, work through this web page and if you are lucky all will become clear.

or you can just copy and paste into the browser if you prefer.
