a) 76
\n" ); document.write( "b) 2.970
\n" ); document.write( "c) 16400 (0's are not considered significant figures, unless you have a number such as 5803.7)
\n" ); document.write( "d) If you know 676 = 26^2 = (13*2)^2, then 676 factors to 13*13*2*2.
\n" ); document.write( "e) 3(a - 6b)
\n" ); document.write( "
\n" );
