Algebra.Com's Answer #171202 by unlockmath(1688) You can put this solution on YOUR website! Hello, \n" ); document.write( "First let's distribute so it looks like this: \r \n" ); document.write( "\n" ); document.write( " 5a^3(8a) - 5a^3(6a) (Note: When I put ^3 it means to the third power.)\r \n" ); document.write( "\n" ); document.write( "Now, we'll multiply each one out. \r \n" ); document.write( "\n" ); document.write( " 40a^4 -30a^4\r \n" ); document.write( "\n" ); document.write( "Since these are like terms we can subtract them. \r \n" ); document.write( "\n" ); document.write( " Answer is 10a^4\r \n" ); document.write( "\n" ); document.write( "There is another way and maybe shorter for you which is to do the calulation inside the parenthesis like this. \r \n" ); document.write( "\n" ); document.write( " 8a - 6a = 2a\r \n" ); document.write( "\n" ); document.write( "Then just multiply 5a^3(2a) = 10a^4\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "RJ Toftness \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
