$\"root%283%2C8%5E2%29\"$
\n" ); document.write( "Yes they are all equivalent.
\n" ); document.write( "And it does not matter whether you square first or find the cube root first
\n" ); document.write( "^2 means square
\n" ); document.write( "^!/3 means cube root
\n" ); document.write( "The denominator tells you it is a root.
\n" ); document.write( "The numerator tells you to square or cube.\r
\n" ); document.write( "\n" ); document.write( "It can be even more fun if there is a minus sign
\n" ); document.write( "The minus sign tells you to take the reciprocal.
\n" ); document.write( "2^(-1) means 1/2
\n" ); document.write( "2^(-1/2) take the square root of the reciprocal. sqrt(1/2)
\n" ); document.write( "You should have a lesson already or soon on fractional and negative exponents.\r
