document.write( "ok i already know that -6 and 13= 7 and that when you divide exponents you subtract top and bottom so 7 -9 =-2\r

document.write( "the answer is 1.088 * 10 ^-2 i do know how -2 came about but can someone show me how the 1.088 came about because 6.8 * 9.6=65.28 /3=10.88 can anyone show me why the first part of the answer is 1.088? and not 10.88 \n" );
