Find range to function: S(t) = ^4√(t^2+16) in interval form. That is a fourth root in the square root symbol.

\n" ); document.write( "rewrite equation:\"y=%28t%5E2%2B16%29%5E%281%2F4%29\"
\n" ); document.write( "interchange y and t and solve for y
\n" ); document.write( "\"t=%28y%5E2%2B16%29%5E%281%2F4%29\"
\n" ); document.write( "\"t%5E4=%28y%5E2%2B16%29\"
\n" ); document.write( "y^2=t^4-16
\n" ); document.write( "y=±√t^4-16)
