\n" ); document.write( "\n" ); document.write( "I understand that 8^3 equals 1/512, just not what steps they took. Is there an easy way to figure out the exponential form of a number? Also, why did the exponent become negative at the end step?\r

\n" ); document.write( "As to 512 being 8^3 ... some just know that...
\n" ); document.write( "others arrives at that by experimenting dividing 512 by logical selections.. like an 6 or 8
