(2sqrt (x-7))^2
\n" ); document.write( "note that sqrt(x-7) = (x-7)^(1/2)
\n" ); document.write( "now return to the problem
\n" ); document.write( "(2*(x-7)^(1/2))^2
\n" ); document.write( "we multiply exponents and get
\n" ); document.write( "2^2 * (x-7) = 4x - 28\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
