(-2^2)^3 = ?
(-2^3)^2 = ?
(-2^3)^3 = ?
If you put these into your calculator just as is they will be neg, pos, neg repectively.
If I do them in my head they will be pos, pos, neg respectively.
Since only the first one will be different I will try to show you why
(-2^2)^3 = ?
The calculator will treat this like (-1*2*2)^3 = -64
I would treat it like (-2*-2)^3 = 64
I think the second way is the convention on how it should be done but it is always wise to put in brackets to show whether on not you want the minus sign inclued in the squaring.
Does this answer your question?
