Answer:
The expression equivalent to is
Step-by-step explanation:
To answer this question, we notice that we have two factors multiplying each other. On one hand we have 3⁷, and on the other hand we have 3⁻⁴.
As t<u>he two factors are powers of the number 3</u>, <em>we have the following identities:</em>
and
<u>which discard that expression</u>. We also know that if we multiply two factors with the same sign, we would get a positive number, so <u>this discards the expression 3⁷x (-3⁴)</u>, as this resulting number will be negative (and 9 is positive).
Finally, <em>we can write the following identity</em>
Therefore the correct answer is
