7x^2/3 * 9/14x
7x^2/3 * 9/14x =9/2*x^(2/3)*x =(9/2)x^(5/3)
\(7x^{2/3}\cdot \dfrac{9}{14x}\\ =\dfrac{9}{2x^{1/3}}\)
Or you mean this one:
\(7x^{2/3}\cdot \dfrac{9}{14}x\\ =\dfrac{9x^{5/3}}{2}\)
And, if you mean this one:
\(\dfrac{7x^2}{3}\cdot \dfrac{9}{14}x\\ =\dfrac{3x^3}{2}\)
Also you may mean this one:
\(\dfrac{7x^2}{3}\cdot \dfrac{9}{14x}\\ =\dfrac{3x}{2}\)
You covered all the bases LOL
