Answer:
[tex]x = 9 {a}^{6} [/tex]
Step-by-step explanation:
[tex] = > {3a}^{3} x = 27 {a}^{9} [/tex]
[tex] = > {a}^{3} x = \frac{27a^{9} }{3} [/tex]
[tex] = > {a}^{3} x = 9a ^{9} [/tex]
[tex] = > x = \frac{9 {a}^{9} }{ {a}^{3} } [/tex]
[tex] = > x = 9a^{9 - 3} [/tex]
[tex] = > x = 9 {a}^{6} [/tex]
hence, the answer is x = 9a⁶.
