 \:\:  \underline{\underline{\bf{\large\mathfrak{~~Solution~~}}}}

 \frac{ \sqrt{5} +  \sqrt{3}i  }{ \sqrt{5} -  \sqrt{3} i }  \\  =  \frac{( \sqrt{5}  +  \sqrt{3} i) {}^{2} }{( \sqrt{5} +  \sqrt{3}i)( \sqrt{5}  -  \sqrt{3}i)   }  \\  =  \frac{5 + 3 +  \sqrt{15}i }{5  + 3}  \\  =  \frac{8 +  \sqrt{15}i }{8}  \\  = 1 +  \frac{ \sqrt{15} }{8} i

here a=1

b=√15/8
