document.write( "(3,000)^3. When solving the problem I multiplied 3,000 x 3,000 x 30000= 270,000.00. I wrote the scientic notation as 2.7 x 10^9 was I correct \n" );

Algebra.Com's Answer #173273 by solver91311(24713) You can put this solution on YOUR website! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "In the first place 270,000.00 is not correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "3000 times 3000 times 3000 is 27,000,000,000. The three 3s give you the 27 and the nine zeros give you nine zeros.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then you wrote \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Start with 2.7 and then move the decimal point 9 places to the right:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2,700,000,000. Compare that to 27,000,000,000. Ten times too small. So what you need is: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You were off because 3 cubed is 27, but you are writing 2.7\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
