Question 1042928
{{{9sqrt(3x^9)-3x^4sqrt(27x)}}}



{{{9sqrt(x^8*3x)-3x^4sqrt(9*3x)}}}



{{{9sqrt(x^8)*sqrt(3x)-3x^4sqrt(9)*sqrt(3x)}}}



{{{9*x^4*sqrt(3x)-3x^4*3*sqrt(3x)}}}



{{{9x^4*sqrt(3x)-9x^4*sqrt(3x)}}}



{{{(9x^4-9x^4)*sqrt(3x)}}}



{{{(0x^4)*sqrt(3x)}}}



{{{(0)*sqrt(3x)}}}



{{{0}}}



-------------------------------------------



So in the end, {{{9sqrt(3x^9)-3x^4sqrt(27x)}}} simplifies to {{{0}}}



In other words, {{{9sqrt(3x^9)-3x^4sqrt(27x)=0}}} for real values of x such that {{{x>=0}}}
