Not sure what you mean by "Dr". Do you mean the derivative of r with respect to x, 
or 
? Or do you want the differential of r, 
?
\(4^{(2x\,+\,1)}\))
or
\(4^{(2x\,+\,1)}\)\,dx)

}\ -\ 8\ =\ 0)
}\ =\ 8)
}\)\ =\ \log_4(8))
\log_4\(4)\ =\ \log_4(8))
\ =\ \log_4(8))
\,-\,1}{2})
Since ^3\ =\ 8)
, \ =\ \frac{3}{2})
