Algebra.Com's Answer #106547 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! Rules for exponents allow you to convert a \"negative\" power to a positive power by simply moving either: \n" ); document.write( "from the \"numerator to the denominator\" \n" ); document.write( "or \n" ); document.write( "from the \"denominator to the numerator\" \n" ); document.write( ". \n" ); document.write( "For example: \n" ); document.write( "if you have: \n" ); document.write( "x^(-3) this is equal to 1/x^3 \n" ); document.write( "if you have: \n" ); document.write( "1/x^(-3) this is equal to x^3 \n" ); document.write( ". \n" ); document.write( "Your problem: \n" ); document.write( "7 to the negative 3rd power \n" ); document.write( "is written as: \n" ); document.write( "7^(-3) \n" ); document.write( "is the same as: \n" ); document.write( "1/7^3 \n" ); document.write( ". \n" ); document.write( "1/7^3 = 1/343 \n" ); document.write( "or in decimal \n" ); document.write( "0.0029154... \n" ); document.write( " |
