document.write( "Question 103991: I need to know how to solve a problem. I no the answer but i dont no how to expain. the prolem shows a tiny 3 almost ontop of the square root symbol then the square root -243 which i have to simlify. the answer is -6 but i dont no how to explain how i got my answer! please help me!!!!! \n" ); document.write( "

\r
\n" ); document.write( "\n" ); document.write( "\"root%283%2C-243%29\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The goal of simplifying expressions with third roots is to factor the radicand into a product of two numbers.
\n" ); document.write( "One of these two numbers must be a value in which you can take the third root and still get a rational number. \r
\n" ); document.write( "\n" ); document.write( "So let's list the factors of -243\r
\n" ); document.write( "\n" ); document.write( "Factors:\r
\n" ); document.write( "\n" ); document.write( "1, 3, 9, 27, 81, 243\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice how 27 is the largest value in which you can take the third root and still get a rational number, so lets break -243 down into -27*9\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"root%283%2C-27%2A9%29\" Factor -243 into -27*9
\n" ); document.write( "
\n" ); document.write( "\"root%283%2C-27%29%2Aroot%283%2C9%29\" Break up the roots using the identity \"root%28n%2Cx%2Ay%29=root%28n%2Cx%29%2Aroot%28n%2Cy%29\"
\n" ); document.write( "
\n" ); document.write( "\"-3%2Aroot%283%2C9%29\" Take the third root of -27 to get -3
\n" ); document.write( "
\n" );
