Algebra.Com's Answer #794121 by CoolRekt(53) ![]() You can put this solution on YOUR website! Choice B is correct. It's like changing something to a negative. A is wrong since it just changes the exponent, not the base. C is wrong since it just swaps the numbers backwards, not making it a negative. D is wrong because 2 cannot be opposites of a fraction (especially if it isn't a negative).\r \n" ); document.write( "\n" ); document.write( "CoolRekt \n" ); document.write( " |
