Prove that any number raised to the 0'th power equals 1.
\n" ); document.write( "

\r\n" );
document.write( "That's not quite true because  is undefined, not 1.\r\n" );
document.write( "\r\n" );
document.write( "But any other number to the zero power is indeed 1.\r\n" );
document.write( "\r\n" );
document.write( "The reason it is 1 is because you can take any non-zero exponent,\r\n" );
document.write( "say, 7, and consider this:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "That must equal 1 because when you divide a number by itself,\r\n" );
document.write( "you must get 1. So\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now if the law of subtraction of exponents is to hold true, then\r\n" );
document.write( "if we do that same problem by subtracting exponents we get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So \r\n" );
