Answer:
[tex]8x^{3} [/tex]
Step-by-step explanation:
Solution:
[tex]\frac { 72 x ^ { 9 } } { 9 x ^ { 6 } }[/tex]
[tex]\left(72x^{9}\right)^{1}\times \left(\frac{1}{9x^{6}}\right) [/tex]
[tex]72^{1}\left(x^{9}\right)^{1}\times \left(\frac{1}{9}\right)\times \left(\frac{1}{x^{6}}\right) [/tex]
[tex]72^{1}\times \left(\frac{1}{9}\right)\left(x^{9}\right)^{1}\times \left(\frac{1}{x^{6}}\right) [/tex]
[tex]72^{1}\times \left(\frac{1}{9}\right)x^{9}x^{6\left(-1\right)} [/tex]
[tex]72^{1}\times \left(\frac{1}{9}\right)x^{9-6} [/tex]
[tex]72^{1}\times \left(\frac{1}{9}\right)x^{3} [/tex]
[tex]72\times \left(\frac{1}{9}\right)x^{3} [/tex]
