write each equation below in simplest radical form. show your steps.
\n" ); document.write( "7. square root of 4x to the 8th power
\n" ); document.write( "\"sqrt%284x%29%5E8\"
\n" ); document.write( "we cab rewrite using fractional exponents as
\n" ); document.write( "\"%28%284x%29%5E%281%2F2%29%29%5E8\"
\n" ); document.write( "this becomes
\n" ); document.write( "\"%284x%29%5E4\"
\n" ); document.write( "\"256x%5E4\"
\n" ); document.write( "--
\n" ); document.write( "8. square root of 28
\n" ); document.write( "\"sqrt%2828%29\" = \"sqrt%284%2A7%29\" = \"sqrt%284%29+%2A+sqrt%287%29\" = 2* sqrt(7)
\n" ); document.write( "--
\n" ); document.write( "9. square root of 27a cubed
\n" ); document.write( "\"sqrt%2827a%5E3%29\" = \"sqrt%2827%29%2Asqrt%28a%5E3%29\" = \"3sqrt%283%29%2Aasqrt%28a%29\" = 3asqrt(3a
\n" ); document.write( "
\n" );
