Answer:
9
Step-by-step explanation:
So in this problem, we are multiplying exponents, with the same base.
To solve this problem, we must know the Laws of Exponents, which states that when multiplying exponents with the same base, keep the base the same and add the exponents.
So we have:
[tex]3^{7} * 3^{-1} * 3^{-4} \\[/tex]
Use the Laws of Exponents:
[tex]3^{2}[/tex]
Simplify:
[tex]9[/tex]
