Question 688751
{{{sqrt (50x^7y^7)}}} ...write {{{sqrt(50)}}} as{{{sqrt(2*25)=sqrt(2*5^2)=5sqrt(2)}}}


={{{5sqrt (2)sqrt (x^7)sqrt (y^7)}}}...........write {{{sqrt(x^7)}}} as {{{sqrt((x^3)^2*x)=x^3*sqrt(x)}}}...do same with {{{sqrt(y^7)}}}



={{{5sqrt (2)*x^3sqrt (x)*y^3sqrt (y)}}}


={{{5x^3y^3*sqrt (2)*sqrt (x)*sqrt (y)}}}
