Algebra.Com's Answer #193189 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! (-3)^5 = -243 \n" ); document.write( "So the 5th root of -243 is -3. \n" ); document.write( "------------------- \n" ); document.write( "6^5 = 7776 \n" ); document.write( "Odd powers of negatives are negative. \n" ); document.write( "(-6)^5 = -7776 \n" ); document.write( "--------------- \n" ); document.write( "(-7776)^(1/5) = -6 \n" ); document.write( "(-6)^2 = +36 \n" ); document.write( "--------------- \n" ); document.write( "Calculators use logs for internal calculation, which don't handle negative numbers in most cases (most calculators). \n" ); document.write( " \n" ); document.write( " |
