A)  \sqrt\frac{9}{16} =   \frac{\sqrt 9}{\sqrt 16}       =  \frac{3}{4}
    

b)  \sqrt\frac{256}{324} = \frac{\sqrt 256}{\sqrt 324}   =  \frac{16}{18} =  \frac{8}{9}
   

c)  \sqrt\frac{100}{169}  = \frac{\sqrt 100}{\sqrt 169}  \frac{10}{13}

d) 
 \sqrt\frac{64}{49} =\frac{\sqrt 64}{\sqrt 49}  =  \frac{8}{7}
