Best ResponseYou've already chosen the best response.1\[\frac{3\sqrt x}{9x}\] factorize the denominator use \[(a+b)(ab)=a^2ab+bab^2=a^2b^2\] cancel common factors

Best ResponseYou've already chosen the best response.1your looking at the numerator (bottom bit of the fraction) you should be looking at the denominator ( the bottom bit of the fraction) \[9x=(\cdots)(\cdots)\]

Best ResponseYou've already chosen the best response.1not quite\[a^2b^2=(a+b)(ab)\] so\[9x=3^2\sqrt x^2=\]

Best ResponseYou've already chosen the best response.1\[9x=3^2\sqrt x^2=(3+\sqrt x)(3\sqrt x)\]

Best ResponseYou've already chosen the best response.1so\[\frac{3\sqrt x}{9x}=\frac{3\sqrt x}{(3+\sqrt x)(3{\sqrt x)}}\]\[\qquad\qquad =\frac{\cancel{3\sqrt x}}{(3+\sqrt x)\cancel{(3{\sqrt x)}}}\]

Best ResponseYou've already chosen the best response.1almost \[(a^3+b^3)=(a+b)(a^2ab+b^2)\]
