break it apart
\n" ); document.write( "sqrt(32)=sqrt(2)(sqrt(16))=4 sqrt(2)
\n" ); document.write( "every 2 in an exponent under the radical (if square root) may be removed and become the variable to the first power. sqrt(k^7) becomes k^3*sqrt(k), the remainder left behind.
\n" ); document.write( "sqrt(q^8)=q^4.
\n" ); document.write( "multiply everything together to get 4*k^3*q^4*sqrt(2k), noting how the two radical terms are just combined under one radical\r
\n" ); document.write( "\n" ); document.write( "do the same for cube roots
\n" ); document.write( "cube root of -64 is -4
\n" ); document.write( "for cube root of a^8, pull THREE a's out and make it the variable to the first power.
\n" ); document.write( "cube root of a^8=a^2*cube root (a^2), the remainder is 2.
\n" ); document.write( "This is -4a^2 cube root (a^2)
\n" ); document.write( "
\n" ); document.write( "
\n" );
