Hello, this isn't really a physics question but I'm getting pretty desperate and you guys have always been able to help me out before :)
1. Homework Statement

I believe I'm suppose to use the Laws of Exponents.
For the first set possibly
but not sure as its addition in the question but can't find any laws with revolve around addition.
for the second set of questions I'm fairly certain its
once again but I'm just not 100% sure and I'm also not 100% sure what the question is actually asking.

3.2 + 0.007 = 3.27
10 x -4 + 10-2 = 10-6
3.27 x 10-6
for the second set.
82x 2-3=
82= 64
2-3= 0.125
64 x 0.125 = 8
But now I'm not sure what to write, it asks for it as a power of 2? Does it just mean write 23.
If anyone could help would be greatly appreciated.
