Best ResponseYou've already chosen the best response.02*2*2 = 8. I made this 8 positive since the 2 was in brackets. I then took 8  (3) which is 11.

Best ResponseYou've already chosen the best response.0Alright, if your number or variable has an odd power = takes the sign of the variable in the brackets . If your number or variable has an even power = answer always positive. and you must know the following rules: ()() = + ()(+) =  (+)(+) = + Give it a try now ^_^

Best ResponseYou've already chosen the best response.08  (3) = 5. I think where my confusion lies is I thought if you have negative squares, the answer is positive if the base is in parentheses and negative if it is not. But as I type this, I am thinking that ONLY applies to squares and not all exponents?

Best ResponseYou've already chosen the best response.0a square is an "even" exponent; and all even exponents give you a positive result.
