Recognize that the sqrt function is the same as raising something to the  1/2 power

 

1st one     sqrt( 50r^2s^4) = (50r^ s^4)^1/2   =  r^(2*1/2) s^(4*1/2)  50^(1/2)   = r s^2 sqrt(50)  = r s^2 sqrt(25*2) = 5 r s^2 sqrt (2)

 

   DO you see?    Try the next one...

         

       x^(3*1/2)   realize = x^3/2 =   x  sqrt(x)
