Answer:
The answer to your question is: log₇ (
)
Step-by-step explanation:
log₇ x + log₇ y - log₇ z
First he must use the product rule that says:
log a x + log a y = log a xy
Then, he must use the quotient rule that says
log a x - log a y = log a (![\frac{x}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D)
He did not use these rules that's why his answer is incorrect.
The correct answer is:
log₇ (xy) - log₇ z
log₇ ![\frac{xy}{z}](https://tex.z-dn.net/?f=%5Cfrac%7Bxy%7D%7Bz%7D)

Answer:
The sum is the third answer
Step-by-step explanation:
you add together the numbers that are in the same spot in both matrixes.
-3 + -4 0 + 2
5 + -1 -7 + 8
That would give you
-7 2
4 1
The answer is 1,000. 500(2)= 1000
