We want to find an equivalent expression to the given one.
We will see that an equivalent expression to the given one is 3^3 or 27.
Let's see how to solve this problem.
First, two expressions are equivalent if the expressions represent the exact same thing.
So if we only rewrite the given expression, we will get an equivalent expression.
To rewrite it, we can use the exponent property:
[tex]a^n*a^m = a^{n + m}[/tex]
Then the given expression:
[tex]3^7*3^{-4}[/tex]
Can be rewritten as:
[tex]3^{7 + (-4)} = 3^3 = 27[/tex]
Then the equivalent expression to the given one can be 3^3 or 27.
