Hello, I'm trying to complete this homework
< link to objectionable page removed >
and I'm really stuck right now. I understand I'm meant to use exponents laws to work it out but I'm not sure which ones and how to finish off the question (Write as a power of 2). For the first one I'm totally lost because I can't find an exponent law which uses addition. For the second question I think I understand the first one this I what I've done so far but I'm completely lost on how to do the second.
82 x 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.
