Answer:

343

Step-by-step explanation:

[tex]\frac{7^{12} * 7^{9}}{(7^{6})^{3} }[/tex] is the equation.

1. You can add the two exponents in the numerator --> [tex]7^{21}[/tex]

2. You can multiply the exponents in the denominator --> [tex]7^{18}[/tex]

(the equation is now [tex]\frac{7^{21} }{7^{18} }[/tex])

3. Subtract the exponents to get [tex]7^{3}[/tex]

[tex]7^{3}[/tex] = 343
