Simplify the radical. Assume that all variables represent nonnegative real numbers.
\n" ); document.write( "squre root 169m^21n^8
\n" ); document.write( "-----------
\n" ); document.write( "169 = 13^2
\n" ); document.write( "m^21 = (m^10)^2*m
\n" ); document.write( "m^8 = (n^4)^2
\n" ); document.write( "
\n" ); document.write( "
\n" );
