The correct answer is B
ella [17]3 years ago
5 0

Answer:

B

Step-by-step explanation:

Recall the product property of exponents, where:

x^a\cdot x^b=x^{a+b}

In our expression, x is 3, a is -8, and b is 4. Thus:

3^{-8}\cdot 3^{4}=3^{-8+4}

Add in the exponent.

=3^{-4}

So, our answer is B.

And we're done!
