Do the second and the third first \n" ); document.write( "2.4 x 10^-5 or 2.4 E -5 (e for exponent)/1.2 E-3, put a decimal between the 1 and 2 and count back 3 to the left so that is 10^(-3) or E-3. \n" ); document.write( "Then divided 2.4/1.2 or 2 and E-5 by E-3 which is E-2, make exponent positive when go across fraction. \n" ); document.write( "so adding 9 E-3 to 2 E-2. \n" ); document.write( "Adding in scientific notation is useful if they have the same exponent, not otherwise. \n" ); document.write( "0.009+ \n" ); document.write( "0.02\r \n" ); document.write( "\n" ); document.write( "0.029 ANSWER \n" ); document.write( " |
