Question 156704
{{{sqrt((50x^3)/(81y^8))=(sqrt(50x^3))/(sqrt(81y^8))=(sqrt(25*2*x^2*x))/(sqrt(81*y^2*y^2*y^2*y^2))=(sqrt(25)*sqrt(2)*sqrt(x^2)*sqrt(x))/(sqrt(81)*sqrt(y^2)*sqrt(y^2)*sqrt(y^2)*sqrt(y^2))=(5*sqrt(2)*x*sqrt(x))/(9*y*y*y*y)=(5x*sqrt(2x))/(9*y^4)}}}



So {{{sqrt((50x^3)/(81y^8))=(5x*sqrt(2x))/(9*y^4)}}} where every variable is positive.
