HollyinNNV Posted April 13, 2011 Share Posted April 13, 2011 (Larson, Algebra II, 2nd Ed.) Section 4.1 #8 1 _ -8 (to the -2 power) We keep getting the answer 64. But the book gives -64 as the answer. Can someone pretty please help us out.:) TIA! Holly Quote Link to comment Share on other sites More sharing options...
Jann in TX Posted April 13, 2011 Share Posted April 13, 2011 the negative is not included in the square. If it were written (-8)^2 then the negative would have been included. Quote Link to comment Share on other sites More sharing options...
Lawana Posted April 13, 2011 Share Posted April 13, 2011 Are there parentheses around the -8? If not, then I take it as the negative of the inverse of 8^-2, or -64. Quote Link to comment Share on other sites More sharing options...
