Question 368347
{{{sqrt(50x^3) - x*sqrt(128x) + sqrt(98x^3)=sqrt(50)sqrt(x^3) - sqrt(128)*sqrt(x^3) + sqrt(98)sqrt(x^3)}}}
{{{sqrt(50x^3) - x*sqrt(128x) + sqrt(98x^3)=(sqrt(50)-sqrt(128)+ sqrt(98))*sqrt(x^3)}}}

{{{sqrt(50x^3) - x*sqrt(128x) + sqrt(98x^3)=(5*sqrt(2)-8*sqrt(2)+ 7*sqrt(2))*sqrt(x^3)}}}
{{{sqrt(50x^3) - x*sqrt(128x) + sqrt(98x^3)=highlight(4*sqrt(2)*sqrt(x^3))}}}
