Algebra.Com's Answer #19350 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! You are doing fine when you wrote: \n" ); document.write( "(m^8-5)(m^8+5)=0 \n" ); document.write( "Therefore m^8=5 or m^8=-5 \n" ); document.write( "m=5^(1/8)= 1.223.. \n" ); document.write( "You could also say m^8+5=0 \n" ); document.write( "So, m^8=-5. This is true only \n" ); document.write( "if m is a complex number. \n" ); document.write( "I'm not saying the above is the only \n" ); document.write( "way you could solve m^16-25=0; it depends \n" ); document.write( "on what level of mathematics you are studying. \n" ); document.write( "But your writing (m^8-5)(m^8+5)=0 is the way \n" ); document.write( "to start. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
