That exponent on a number, like 10, tells
\n" ); document.write( "you how many of that number you are going
\n" ); document.write( "to multiply.
\n" ); document.write( "For example 2^3 means 2*2*2.
\n" ); document.write( "So, 10^9/10^7 means you have nine tens in the
\n" ); document.write( "numerator and seven in the denominator.
\n" ); document.write( "So, seven of the 10's in the numerator get
\n" ); document.write( "canceled leaving you with two or 10^2.
\n" ); document.write( "Similarly with the 2's. You have eight
\n" ); document.write( "in the numerator and 3 in the denominator.
\n" ); document.write( "You end up with 5 two's in the numerator or
\n" ); document.write( "2^5.\r
